correctly setup everything in the default run_once runner (#8740)

Browse source 
# Objective

- Fix #8658 
- `without_winit` example panics `thread 'Compute Task Pool (2)'
panicked at 'called `Option::unwrap()` on a `None` value',
crates/bevy_render/src/pipelined_rendering.rs:134:84`

## Solution

- In the default runner method `run_once`, correctly finish the
initialisation of the plugins. `run_once` can't be called twice so it's
ok to do it there
