fdo#54275: Fix GVFS UCP, so saving docs works again

Similar to 8722f0e7ef690205d042c8a6b1fdf342a34ecbe1 "rhbz#895690: Make GIO UCP
less brittle, so saving docs works again" the alternative, older GVFS UCP
(--enable-gnome-vfs --disable-gio, as used e.g. in
distro-configs/LibreOfficeLinux.conf) no longer works well in LO 3.6 and later:

* For one, "getPropertyValues" did not work for non-existing files, just like in
  the GIO UCP case.

* For another, creating the .~XXX# lock file uses "insert" with
  !bReplaceExisting, which apparently never worked for the GVFS UCP.
