adjust error message assertion for TypeError

adjust error message assertion for TypeError

in eee7a3add99df2865e6d907f2 I added a few TypeError
tests, and some python interpreters produce a message like
"join() got an unexpected...", others seem to produce
"Query.join() got an unexpected..."

the pattern is strange, all Python 3.10's seem to return the
class name.  For Python 3.8 and 3.9, my local intepreters
are doing the Python 3.10 behavior but github actions are doing
the older behavior.  Python 3.7 both here and on github actions
are doing the older behavior.

In any case, adjust the regexps to match both.
