Spawning particle effect in PostUpdate crashes

[barsoosayque]

Crate versions bevy version: 0.14.1 bevy_hanabi version: 0.12.2

Describe the bug Spawning a new entity with ParticleEffect component in PostUpdate schedule results in unwrap:

thread 'Compute Task Pool (1)' panicked at /<...>/.cargo/registry/src/index.crates.io-6f17d22bba15001f/bevy_hanabi-0.12.2/src/render/mod.rs:2107:59:
called `Option::unwrap()` on a `None` value

Expected behavior I would expect any schedule to be valid for spawning particle effects.

To Reproduce Here is a diff for examples/spawn_on_command to reproduce this crash:
