Unused assignment when not checking

[QartemisT]

When defining a variable, and then checking if it doesn't exist and overriding it, it flags the original as unused.

Example:

local test = _G["Test"] -- This is flag as unused

if not test then
	test = CreateFrame("Frame", "Test")
end

test:SomeFunc()
