remove unneeded hash from test files (#1119)

In #877 we added a hash to all
test files, so that when we update stack.yaml we could signal to the
website that an exercise has changed and that students should update to
the new version (this used to be a problem in
#864, where students wouldn't
get up-to-date versions of the files)

In #1117, `stack.yaml` was added
as an invalidator, so we no longer need to have this hash.
Used by website in:
