player_movement2 example fails on master

I was trying to figure out how to query for RapierConfiguration, the example seems to have the same problem I ran into.

thread 'main' panicked at bevy_rapier2d/examples/player_movement2.rs:28:43:
called `Result::unwrap()` on an `Err` value: NoEntities("bevy_ecs::query::state::QueryState<&mut bevy_rapier2d::plugin::configuration::RapierConfiguration>")

Thanks for the report! #603 should fix it

Yep, that fixes it!
