Title:
  click chroot create and destroy don't check status of chroot before
  executing the subcommand

Status in click package in Ubuntu:
  Confirmed

Bug description:
  Here's my use case:
  1) create chroot
  2) use it
  3) destroy it

  During the use it phase I have left over mounts, so when I destroy it
  it fails to remove it from the fs but actually destroys the reference
  to the chroot as when I try to delete it again after manually
  unmounting it says it doesn't exist and when I try to create it says
  the filepath already exists.

  $ sudo click chroot -aarmhf -f ubuntu-sdk-13.10 destroy
