I know we (and especially me!) have been adding new MIME types to this test, but I'm now thinking there's not much point, we're essentially duplicating types_map in reverse.

It's useful to have some in here, to test the lookup works, but we don't really need all.

When we have multiple extensions (for example, application/mathematica has .ma, .mb and .na), maybe it's useful to include the test to show which extension it returns.

I'm not suggesting removing all existing ones, but shall we remove the new ones here, other than for application/mathematica?
