Lots of calls to ` traversal.asAdmin().getEndStep()`. Maybe it's smarter to
call it only once..? More like this:
```
// The ProfileSideEffectStep must be the last step, 2nd last step when
accompanied by the cap step,
// or 3rd to last when the traversal ends with a RequirementsStep.
Step endStep;
if (TraversalHelper.hasStepOfClass(ProfileSideEffectStep.class, traversal)
&&
   !((endStep = traversal.asAdmin().getEndStep()) instanceof
ProfileSideEffectStep ||
        (endStep instanceof SideEffectCapStep &&
endStep.getPreviousStep() instanceof ProfileSideEffectStep) ||
        (endStep instanceof RequirementsStep && (
            endStep.getPreviousStep() instanceof
SideEffectCapStep ||
            endStep.getPreviousStep() instanceof
ProfileSideEffectStep {
  throw new VerificationException("When specified, the profile()-Step
must be the last step or followed only by the cap()-step and/or requirements
step.", traversal);
}
```
^ I also removed all the negations, which makes the chained conditions a
bit easier to read IMO.
But all in all this PR looks good to me.
