Robin messes with promises

promises.js

    return new RSVP.Promise(function(resolve, reject) {
      var fileReaders = fileNames.map(function(filename) { 
        return readFile('dist/'+filename);
      });
      RSVP.all(fileReaders).then(function(fileContents) {
        fileUploaders = fileContents.map(function(fileContents, fileIdx) {
          return this._uploadIfNotAlreadyInUploadList(uploadName, fileNames[fileIdx], fileContents);
        });
        RSVP.all(fileUploaders).then(resolve).catch(reject);
      });
    })
    .catch(function(reason) {
      return this._printErrorMessage(reason); // TODO: format this message
    }.bind(this));
