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
