Do not recursivly remove the mount-path after
unmounting it to prevent accidential data removal

Issue #23

@sascha-egerer do you think we should just do this or rather prevent duplicate mounts at the same mountpoint, somehow?

Yes i think a recursive remove is a bad idea anyway.
You mount a share to an existing folder. This folder can contain content but is then overlayed with the mount - so no problem here so far. But if you now unmount and then recursivly remove that folder you may delete data that should not be removed.
You can now say "there should be no user content at this place" but i think it's better to throw an error then removing the data without any information.
So that has not really something to do with the duplicate mount as it may also be a problem if there is local data in that folder.

But yeah i'm not sure if that error has to be catched and must be prepared for a save driver fail...
