Utilize the release callback returned by lockFileSync to release the lock file (!239)

Browse Source 
The error people are getting about a lock file already existing is due to `checkFileSync` returning false if the lock file is "stale".
The default "stale" timeout is 10 seconds, so if a save takes longer than this, the user will end up in a state where they can no longer save.

The documentation for `proper-lockfile` recommends using the callback returned by `lockFileSync` to remove the lock file, so I've switched to using this, and the error no longer occurs with long running save operations
