[Expander] Directory chooser should begin from the directory in input box
|Reported by:||Adek336||Owned by:||korli|
If you have something in the Destination input box, like "/auwacr/4acxcr" and you click the "Destination" button, the directory chooser pops out, but the directory it shows is "/home".
It should be the "/auwacr/4acxcr" directory, to improve user experience in the frequent case that one wants the archive to be expanded to a subdirectory of where the archive is stored.
The same goes to the "Source" button.
