rv/ltl: Do not execute the Buchi automaton twice on start condition 

On start condition of a Buchi automaton, the automaton is executed twice.

This is fine for now, as all the current LTL operators do not care about
this. But it would break the 'next' operator, which will be introduced in a
follow-up patch.

Prepare for the introduction of the 'next' operator, only execute the
automaton once on start condition.
