kernel32/tests: Convert fiber back to thread even when IsThreadAFiber is not available.

[Bernhard Übelacker]

Testbot shows the fiber test failing for Windows 2003 recently.
https://test.winehq.org/data/tests/kernel32:fiber.html

This is probably related to the last change in
http://source.winehq.org/git/wine.git/commit/556fef3dd184e71e1f0345bd8f37259c88a6f078

As Windows 2003 seems to have no IsThreadAFiber the test never
calls test_ConvertFiberToThread.
This leads probably sometimes to the crash now visible.

By calling test_ConvertFiberToThread before return the crash disappears
on Windows 2003.
