Restore previous workspace on application resume (#10813)

William Viktorsson created 2 years ago

Addresses #10812 

Release Notes:

- Launching an empty already-running Zed application now behaves like a
regular startup and respects the user `resume_on_startup` setting.
([#10812](https://github.com/zed-industries/zed/issues/10812)).

See attached showcase which highlights how the previous project can now
be re-opened through both "quit" and "close window".

This has a noticeable performance benefit on startup/project resume
time.

This should also make the behaviour of closing/opening an application
consistent between macOS/Linux/Windows.
