Explicitly delete old logicModule entries from Context.moduleInfo

Browse source 
Creating variants has an optimization to reuse the logicModule of the
original variant as the logicModule of the first new variant.  Using
the same logicModule meant that updating the Context.moduleInfo map
from logicModules to *moduleInfo would overwrite the old entry for
the original variant with the new entry for the first variant.

TransitionMutators will need to keep the original logicModule for
later use, which will require disabling the optimization that reuses
it.  When the first variant is added to the map it no longer overwrites
the original variant.  Excplicitly track the original logicModule and
remove it from the map if necessary.
