Disable thread-safe statics for MSVC 2015: they're broken

Browse Source 
An object that throws in its constructor cannot be reentered. This
violates both C++11 and C++98. It's also a regression from MSVC 2013.

The unit test is renamed to indicate what it really does, as opposed to
a misleading name that was probably a "thinko" on my part.
