This will ensure we don't accidentally cause bustage to graph generation with any of the parameters checked into `taskcluster/test/params`. This was previously being (sort of) tested by the `tgdiff` task. Now that this test exists, we no longer need to rely on it. I removed 'always-target' from the task since this now takes ~25 min to run and which is the new bottleneck for reviewbot turn around times.
