dbhub: Remove remote menu, add push button to remote dock

This commit removes the File -> Remote menu entirely. The only menu item
that was left was the Save to Remote item which is replaces by a button
in the remote dock.

The button is only enabled when a database file is opened and the user
has logged in using a certificate.

Clicking the button opens the same dialog and performs the same actions
as before. The only difference is that we don't use the first client
certificate - no matter which one it is - but instead use the client
certificate that was used for logging in.
