Fix add_ordered_transitions w/o initial state

Previous implementation assumed that the initial state of the state
machine must be specified in the states list.

However, the add_ordered_transitions could be useful also when only a
part of the state machine is wanted to have ordered transactions. Think
for example nested state machine where sub-states of a state is wanted
to be traversed in order, perhaps in a loop.

To fix, allow calling add_ordered_transitions with states argument not
including the initial state. In effect, loop_includes_initial argument
has no relevance if the initial state is not present in the states list.
