Should not check for `pwd == $HOME` on `start`

[Anders Logg (Chalmers)]

When an image is created using fenicsproject create and then started using fenicsproject start, the script should only check that the home directory is not shared on create, since start will only share the pwd at the time of creation. (?) Now one has to cd into some random directory to start a previously created image.
