minimize_wdba() failed to fully minimize some automata.

Browse source 
* src/tgbaalgos/minimize.cc (minimize_wdba): Fix the Löding
algorithm to use colors.  The previous implementation was an
incorrect approximation.
* src/tgbatest/wdba2.test: New file showing two equivalent
formulas that were minimized in automata with different sizes.
* src/tgbatest/Makefile.am: Add it.
