room-message-event: Fix image download

room-message-event: Fix image download

In case of an image the file element has the uri not the body itself.

Without this we see

 15:12:07.2632 cm-room-message-event[981607]:CRITICAL: cm_room_message_event_get_file_async: assertion 'self->mxc_uri' failed

in the logs and the download spinner never stops.

While at that add a docstring to make owner ship transfer more obvious.

This allows me to download images pasted with Element 1.11.64

Testing a bit more the same issue shows for audio and any kind of files so using the same pattern there.

I think we could even drop setting mxc:// intially but maybe @mohammed.sadiq you had a reason for doing it like this initially?

All quiet, merging.
