[test-quadrature][fs1541] Don't test quadrature rules we don't implement.

This worked previously, because we were testing GaussLegendre quadrature rules
first seeding the cache.  Second we were testing GaussLobatto quadrature rules
-- or so we thought: due to FS#1541, the cache would yield the previous
GaussLegendre quadrature rules, even though we requested GaussLobatto.  With
that fixed, the test would try to instantiate GaussLobatte quadrature rules of
up to order 45, even though they are only implemented up to order 31.
