Avoid deleting the workspace when it's still in use.

- From now on, NSFW service disposes after last reference
is removed. No more 10sec delay.
 - Moved the temp workspace deletion to a startup task.
 - Can set initial task for the window from electron-main.
 - Removed the `browser-app`.

Closes #39
