qmake vcxproj generator: Fix extra compilers for single configs

For single config mode (no debug_and_release) extra compilers wouldn't
get added to the vcxproj file.

Single config mode creates a temporary project, and that was incomplete.
Multi config mode, on the other hand, directly operates on the "real
data" and wasn't affected by this problem.
