Sometimes when running the WordPress export/import tools, the excerpts will be empty at the new location. This is because the import tool doesn't remove whitespace from this field, and what was once empty is now a string of tabs and spaces. WordPress will see that the excerpt field has content, even if it's all whitespace, and will assume it's a custom excerpt. To fix, this function runs before the WP filter, and preemptively strips out leading and trailing whitespace from the excerpts.
