Move umount logic from archive_tab.py into existing BorgUmountJob. By @real-yfprojects (#1404)

* src/vorta/borg/umount.py (BorgUmountJob.prepare): Add parameters `mount_point` and optional `archive_name`.
	Handle them correctly.

* src/vorta/views/archive_tab.py : Remove code that can now be found in `umount.py`.
	Translate error messages returned by `BorgUmountJob.prepare`.
