Comment (by SimonKing):
Now things should work.
Changes:
- For letterplace rings, one has to call the parent init later, so that
the conversions that occur in `__init_extra__` work.
- In pushout.py, there is one test where a class is defined as a subclass
of a parent-class-with-category. By consequence, an instance of that class
is not correctly category-initialised.
- I just realise that I forgot some fixes for tests in homset.py. Here is
problematic what I mentioned above: The base ring is not given, but the
category has a base ring, and because of the missing base ring,
`__init_extra__` fails. Fixing it now...
