Title: Fixes perlbrew off when using fish shell

Previously this should report that perlbrew was successfully turned off, but would in fact not do so. Since the PERLBREW_PATH variable was not cleared it would be at the front of PATH and thus perlbrew's perl would be picked up first.

-r is not a valid flag for set, so I'm unsure what it was intended to do.
