Subject: [PATCH] if it is not possible to make the sharing Uri, return a
 placeholder

The receiver of this can at least make some sense of it, versus null or a
blank string.  This prevents crashes where FDroid.repo.address is not yet
set since the wifi was never enabled or it does not have an IP address yet.
