Fix channeled melee or attacks halving trigger rate when dual wielding

[Lilylicious]

Fixes issue from reddit post

Description of the problem being solved:

The check for dual wielding when dealing with channeled skills only checked for the skilltype being melee or attack. Channeled skills are not affected by dual wielding when it comes to their trigger rate.

Steps taken to verify a working solution:

• Check trigger rate before and after fix
• Confirm that the effective trigger rate is not halved when dual wielding with cyclone after fix
