1f743141 (fix #1905: Allow moving unused disks)
we want to check the source drive name for 'unused', but in case of
importing a volume from the 'import' content type (e.g. from esxi),
there is no source drive name. So we have to first check if it's
defined.

i did not add a 'fixes' trailer, because when the patch was written
there was no 'import' content-type where that could have failed.
also at the time the 'import' was written, the patch checking for unused
was not applied yet, so there no fault there too..
