test_matrix_norm incorrect sampling

ord=sampled_from([-float('inf'), -2, -2, 1, 2, float('inf'), 'fro', 'nuc']))

Shouldn't we also sample -1, right now we are sampling -2 twice, seems to me like one of those -2 should be -1. I might be wrong tho.

I am happy to make a PR for the same :)

Thanks for pointing this out @bicycleman15, yea you're right. Would hold of a PR incase @asmeurer was going to rework test_matrix_norm in #101 anywho. Eh I'll just fix it now heh.
