SubmitRuleEvaluator: Simply logic that checks that change and project exist

1. check that change exists

We do not need a local variable for the change, but we can just use
cd.change() after checking that cd.change() is not null.

2. check that project exists

The old code throw a NoSuchProjectException just to catch it can wrap it
into an IllegalStateException, just throw the IllegalStateException
directly.
