Fix potential crash when destroying workspace

`_container_destroy` emits a destroy event, and any listener for this
event should have access to the full container, not a half destroyed
one.

`_container_destroy` also destroys the swayc, so we have to grab a
reference to the sway_workspace so we can free it afterwards.

This also fixes a memory leak where the floating container wasn't freed.

Fixes #2092.
