Title: Issue 2867 lambdify raises

Changed raises() sympy/utilities/tests/test_pytest.py to accept callables instead of compilable strings.

All other changes are to change all calls to raises() to use callables instead of strings.

In the long term, I guess the compilable string variant can be removed, but I left it in for now to allow for a transition period.
