Style/SpaceAfterNot doesn't catch not then parenthesis: ! (foo)

[cgriego]

Expected behavior

This code should have reported an offense for the Style/SpaceAfterNot cop:

@accept_success = ! (model.send(association).empty?)

Actual behavior

No offense was reported. After I ran and auto-corrected Style/RedundantParentheses, then an offense was reported for the auto-corrected code.

@accept_success = ! model.send(association).empty?

This should be an easy fix. Reducing down the problem, ! (model) does not register an offense either. I see that the cop is using regex, so that probably needs to be tweaked. I should be able to have a fix for this soon.
