Transfer shares if no path provided

[juliushaertl]

Path is actually relative to the view and not to the user directory, so checking for null doesn't make any sense.

Fixes a regression by #22116 (comment) which got catched in talk integration tests for shares of transferred files.

Talk tests run fine locally with this.
