Skyler Hawthorne 41bf1d5811 fix(command): write-quit: do not quit if write fails
During write-quit, if the file fails to be written for any reason, helix
will still quit without saving the changes. This fixes this behavior by
introducing fallibility to the asynchronous job queues. This will also
benefit all contexts which may depend on these job queues.

Fixes #1575
