Turning it off for now to avoid crash, further check will
have to be put in place to make sure that the current context

Refactor FileTransfer.afterSuccess to afterTransfer

In order to prevent the deleting of files when MoveFileTransfer
**fails**, it was necessary to provide the callback method with
the number of errors.

Further, to have the number of errors properly reported, it was
necessary to notify of a FILE_EXCEPTION on any exception during
uploadFile.

Depending on other import settings, this could trigger a file
upload, which in the case of in-place import is to be avaoided.
