Remove code guarded with wxUSE_GUI from wxLog unit test

This file is never compiled with wxUSE_GUI==1, so having these tests
here is not really useful.

It's unfortunately that the absence of warnings from wxLogStatus() is
not checked currently, but it doesn't seem worth recompiling the entire
test case or adding a new one just for this.
