EAGLESIX-3157: matcher: fix jshint issues

Fix JSHint issues with new pipeline matcher code ported from 2.6.5 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.

Ya, this seems a little silly sometimes but using JSHint to verify consistency not single or double. Less concerned about which and more concerned about going back and forth every other line.
