Alttp: assert failures in fill_restrictive

[black-sliver]

The following locations (maybe more) have rules that depend on state:

• Turtle Rock - Big Key Chest
• Palace of Darkness - Harmless Hellway
• Palace of Darkness - Big Key Chest
• GT - Map Chest iirc

When filling in fill_restrictive we check with maximum_exploration_state but in push_item we assert with self.state, which seems to be different and fail the assertion. This accounts for quite a few generation failures in my random-yaml testing, so this should probably be fixed. Ping me on discord if you need a reproducer, but I'm pretty sure the difference in state is what makes it crash.
