Set username/domain/password to use only if provided by user

The semantics of ucbhelper::InteractionSupplyAuthentication changed at
some point, so the getUserName(), getRealm() and getPassword() methods
now return non-empty strings only if the user actually changed them.
Check the return values for being non-empty before using them for
gnome-vfs authentication.

From gnome-vfs-authentication.diff, fixes bnc#465102.
