urlmon: add some more tests for FindMimeFromData()

[Austin English]

While debugging http://bugs.winehq.org/show_bug.cgi?id=27115.

Shows that calling FindMimeFromData with NULL for the buffer is valid
for mime: L"text/html" (assuming that url is valid).

Passes WTB (there will be some failures, that already exists for
Win7/64-bit, these are not from my patch).
