Music app issue on import

gistfile1.txt

Music app can't play imported file.
The File is well copied but no entry in MediaStore db.

watch inotify events:
inotifywait -rme modify,attrib,move,close_write,create,delete,delete_self /home/phablet/Music/Imported/2021/09/03

QFile::rename + QFile::copy ( actual content-hub code contentItem.cpp/move method )
/home/phablet/Music/Imported/2021/09/03/ CREATE 094451-pikatchu.wav
/home/phablet/Music/Imported/2021/09/03/ MODIFY 094451-pikatchu.wav
/home/phablet/Music/Imported/2021/09/03/ MODIFY 094451-pikatchu.wav
/home/phablet/Music/Imported/2021/09/03/ CLOSE_WRITE,CLOSE 094451-pikatchu.wav
/home/phablet/Music/Imported/2021/09/03/ DELETE 094451-pikatchu.wav => (QFile::rename fails, thus try to restore state by removing the destination part )
Now "move" method from ContentHub ContentItem.cpp try to use copy:
/home/phablet/Music/Imported/2021/09/03/ CREATE qt_temp.noaGQp
/home/phablet/Music/Imported/2021/09/03/ CLOSE_WRITE,CLOSE qt_temp.noaGQp
/home/phablet/Music/Imported/2021/09/03/ CREATE 094451-pikatchu.wav
/home/phablet/Music/Imported/2021/09/03/ DELETE qt_temp.noaGQp
/home/phablet/Music/Imported/2021/09/03/ ATTRIB 094451-pikatchu.wav


QFile::copy only ( test in content-hub code contentItem.cpp/move method )
/home/phablet/Music/Imported/2021/09/03/ CREATE qt_temp.FWblFL
/home/phablet/Music/Imported/2021/09/03/ CLOSE_WRITE,CLOSE qt_temp.FWblFL
/home/phablet/Music/Imported/2021/09/03/ CREATE 102117-hhhh.wav
/home/phablet/Music/Imported/2021/09/03/ DELETE qt_temp.FWblFL
/home/phablet/Music/Imported/2021/09/03/ ATTRIB 102117-hhhh.wav

QFile::copy ( not on UT ):
/home/xxx/untitled/ MODIFY #3414925
/home/xxx/untitled/ CREATE twa-dev.png
/home/xxx/untitled/ CLOSE_WRITE,CLOSE #3414925
/home/xxx/untitled/ ATTRIB twa-dev.png


copy with filemanager:
/home/phablet/Music/Imported/2021/09/03/ CREATE hhhh.wav

/home/phablet/Music/Imported/2021/09/03/ MODIFY hhhh.wav

copy via cp:
/home/phablet/Music/Imported/2021/09/03/ CREATE tikitildjdjdj.wav
/home/phablet/Music/Imported/2021/09/03/ MODIFY tikitildjdjdj.wav

QFile::rename in content-hub (https://gitlab.com/ubports/core/content-hub/-/blob/ubports/xenial/import/Ubuntu/Content/contentitem.cpp#L229) is not working, fails when trying to remove the source file

AppArmor issue :
apparmor="DENIED" operation="link" profile="com.ubuntu.music_music_2.9.23" name="/home/phablet/Music/Imported/2021/09/03/094451-pikatchu.wav" pid=5310 comm="qmlscene" requested_mask="wacd" denied_mask="wacd" fsuid=32011 ouid=32011 target="/home/phablet/.cache/com.ubuntu.music/HubIncoming/2/094451-pikatchu.wav"

This is intentional rule:
apparmor-easyprof-ubuntu/data/policygroups/ubuntu/16.04/content_exchange
deny @{HOME}/.cache/@{APP_PKGNAME}/HubIncoming/** w,

we could use QFile::copy but that will not trigger the right inotify events
except if QT_NO_TEMPORARYFILE definition is set
