Fix Melee Attack Speed Again (#1653)

# Description

Melee Weapons were accidentally given the wrong attack speed formula
again. It took me awhile of reviewing the entire history, but eventually
I found the line where the wizmerge introduced a new check that used the
old formula.

Also to help prevent this from happening again, I've put in a request to
be set as codeowner for the relevant systems I have significantly
modified.

# Changelog

- fix: Fixed melee weapons having the wrong attack speed
calculations(again)
