make TestSuite work => Make HomSpace
inherit from Homset; remove
UniqueFactory of Homspace,
Homspace.__contains__, make TestSuite
work
Comment:
There is now a different error reported by the patchbot (with identical
patches), but both errors seem totally unrelated.
However, there is a more serious problem: There are cases when a morphism
is not calling `sage.categories.morphism.Morphism.__init__`. And part of
the problem: `QuiverHomspace` does not inherit from `Homset`!!
