run egui pass after bevy_ui

[jakobhellermann]

should fix #52

@Hilku can you confirm by putting

[patch.crates-io]
bevy_egui = { git = "https://github.com/jakobhellermann/bevy_egui", branch = "after-ui-pass" }

in your Cargo.toml?

This is a bit ugly because it uses a hardcoded string out of bevy_ui but I can't think of a better solution right now.

[Hilku]

I tried it, and it seems to be better, but bevy_egui is still sometimes rendered "under" bevy_ui.

I'll merge this until we can have a better fix. @Hilku unfortunately, I wasn't able to reproduce the problem when bevy_egui still gets rendered "under" bevy_ui sometimes. If you have an example, feel free to open a new issue and share it, I'll try to look into it.
