Feature/mongo 2.6.5 jshint tests

Fix JSHint issues with new pipeline test code that was (mostly) ported from the original 2.6.5 mongo code.
Part of an effort to cleanup various JSHint issues in one fell swoop so that we can keep things a bit cleaner going forward.

Whoops. Brute force FAIL. :-/
I tried to be fairly careful about those but I guess I missed some. I'll go fix that real quick.
