[Petra] do not pass min == max range in moveToRange

Original diff D2512

Reported on forum by gameboy:

Units with goal where minrange = maxrange rarely arrive to destination,
because they miss it.
See Todo in unitmotion
Relative part:

In the meantime, one should avoid that 'Speed over a turn' > MaxRange -
MinRange, in case where min-range is not 0 and max-range is not
infinity.

For that reason avoid passing minrange = maxrange from ai.
Also warn in cpp unitmoition when getting this kind of command.
