Fix compilation of LiftJavaScriptSpec.

This broke when we changed the lift JS stuff to use a single LiftRules
FactoryMaker to determine both whether it should be generated and which
settings should be used. The specs are still failing due to mismatches
with the latest JS stuff.
Fix LiftJavaScript specs.

Some stuff was bringing LiftJavaScript into alignment with what ths
specs expected, and some bringing the specs into alignment with what
LiftJavaScript now does.
