Musicplayer application can not display DRM files of internal storage.

Make DRM-protected files transferred over MTP be detected.
Previously it was inserted into the database as MEDIA_TYPE_NONE,
the result of this was that the file was not detected properly.
With this fix the file is scanned from the beginning.
