Revert "test: hush: dollar: fix bugous behavior"

What we were doing here amounts to simplifying the code for the new hush
parser, and the workarounds are required when using the old one. As we
have returned to having the old parser be default for now, we must undo
this so that the test passes again.

This reverts commit 6c2f753f4ad3dcee60190949d1286736a6d51d17.
