Does not remember the selected partitions

[mmadia]

Usability issue. In short, launching drive setup will cause Installer to forget which partitions the user had selected prior to clicking "Setup Partitions"

To reproduce: Start Installer via Terminal.
Select any partition other than the first one listed.
Click "Setup partitions" to launch DriveSetup.
Exit DriveSetup.
Notice the TargetVisitor::Visit(BPartition *) and similar output.
Notice the Install from has changed from the user's selection to the first listed partition.

Expected results: Upon exiting DriveSetup, Installer should still retain the user's selected partition for "Install to:"

Note: "Onto:" is also lost.

The selections are lost for at least good reason: the changes possibly made in DriveSetup could render the selections wrong. I think it's good to have to user double check the selection in this regard.

Is this bug still valid ?

For Onto, it's in the moment intended to lose the selection and revert to "Please Choose Target". For "Install From", Installer could try to remember the partition. So I'd leave the ticket open.
