[Lemon] Unity Bug Reequip

Shows when Unity bugs out and presents a Button to re-equip Unity.

Thanks to Fail US-Ragnaros for his https://wago.io/bMIfX1ISl and figuring out how Unity bugs out and presenting a simple Weakaura to show it.

This WeakAura takes it a step further with adding a Button to fix the Unity legendary by reequipping it.
