Test that the stash apply command updates the work tree as expected for changes which don't result in conflicts. To make that work add a helper function that uses read-tree to apply the changes of the target commit to the work tree, then stashes these changes and at last applies that stash. Implement the KNOWN_FAILURE_STASH_DOES_IGNORE_SUBMODULE_CHANGES switch and reuse two other already present switches to expect the known failure that stash does ignore submodule changes.
