adding failing tests

[yurique]

SubclassingSpec I'm not sure if it's supposed to work like this, but I was expecting it :)

WeirdCaseSpec it fails like this (if the code is uncommented):

[error]  [Factorio]: Cannot construct an instance of an abstract class [factorio.WeirdCaseDomain.Thing], provide a concrete class binder or an instance provider.
[error]
[error] While analyzing path:
[error] 0: factorio.WeirdCaseDomain.WantSomething ->
[error]
[error]     val assembler = Assembler[WantSomething](new TestBlueprint)

but the Thing is bound:

    @provides
    def thing: Thing = new RealThing
