Unclear error message when putting an alias on the exclude list

[mateuszbaran]

Consider the following example:

julia> Aqua.test_all(Aqua; ambiguities=(exclude=[Aqua.ExcludeSpec],))
Method ambiguity: Error During Test at /home/mateusz/.julia/packages/Aqua/tHrmY/src/Aqua.jl:67
  Got exception outside of a @test

Currently putting an alias on the exclude list gives a hard-to-interpret error message. I would suggest either allowing aliases or writing in the error message that alias usage may be the cause of the issue.
