Mislabeling of weapon skills

[Linkaaaaa]

Examples of Dagger 3 and Greatsword 5 on a Harbinger page

Greatsword 5 is labeled correctly on a Reaper page but Dagger 3 does not.

Dagger 3 is not labeled correctly even on Core Necromancer

May or may not be related to #126

Code to review, may be caused by the specialization check, breaking with weapon mastery, it doesn't explain the mislabeling of dagger though. https://github.com/HardstuckGuild/GW2-Tooltips.js/blob/master/src/TooltipsV2.ts#L899

While looking into a better labeling logic, dual skills should be looked into too.

A dual skill should display [Main set] / [Off set] [number 3] for Thief and Weaver, don't remember if there are other classes that work like that.

Examples:

This should be (Dagger + Pistol 3)

(Dagger + Dagger 3)
