If there is an error during the attempt of building a builtin prior (methods implemented in SpaceBuilder), the builder assumes the expression is not a builtin prior and then tries to create a scipy.stat prior which also fails. The error message is then that the name of the expression is not a valid prior. We should instead explicitly verify if the name of the prior is one that is builtin and then try to build it without silencing error messages. This way we get the correct error message for the prior.

You could use the match argument of raises instead of checking if the value is in the exception message, I think.
(That might be only true for pytest.warns though, not 100% sure).

Indeed. This test is looking at two different parts of exc.value however.
