fix($parse): fix CSP nested property evaluation, and issue that prevented its tests from failing

cspSafeGetterFn incorrectly returned undefined if any of its key parameters were undefined. This
wasn't caught by the $parse unit tests because of a timing problem where $ParseProvider was reading
the CSP flag before the tests manually set it, so the CSP property evaluation tests never ran. Add
test that verifies evaluation of nested properties of multiple lengths.

- use only one IIFE and a ternary op in it, instead of invoking separate IIFEs in if-else
(this also completely fixed the same issue closed by PR #3597)
- also add a spec to verify usage of '$' property in expression object (e.g. `{$: 'a'}`)

Closes #5637

This reverts commit caeb7402651702cd13df2f1594e9827439a8b760.

The commit breaks Google apps because most don't use closure compiler
with the ES5 mode flag on. We are investigating a solution...
