cleanup check_victory in ai actions

do_execute which calls run_in_synced_context can throw end_level
exception because run_in_synced context calls check_victory. So we don't
need the additional check_victory in action_result::execute anymore.
remove check_victory in play_human_turn

we don't need these because we call check_victory at the end of the
synced_context.

I removed them because check_victory assumes that "this code is run
rarely" which is not the case if we call it there.

Move animationless moving unit hiding to a more appropriate place

Unit hiding is usually done in replace_temporary, which is called by
proceed_to. As proceed_to exits at the beginning if animate is false, this
would seem like a good place to hide the unit, but it is also unhidden during
this function. This means that was_hidden_ is set multiple times, with the
second time overwriting it with the temporary state of being hidden.
As animate remains false for the entire lifetime of the unit mover, we hide it
at the start and let finish unhide it again.
