image-copy: Do not panic on ImageCaptureSourceKind::Destroyed

Browse source 
The way this was handled previously is incorrect. We should still handle
creation of a capture session, just send `stopped` when it is created.

This can be tested by creating a capture source and session for a
workspace that has been removed. Toplevel and output sources have a
different issue in `smithay`: https://github.com/Smithay/smithay/pull/1961

Should fix https://github.com/pop-os/cosmic-epoch/issues/3319.
