perf: Fix double configuration flicker on fast device change (#2537) 
* fix: Fix double configuration on device change

Fixes a situation that happened on every device change (or initial mount) where the device was configured after the session, separately, instead of just all at once causing an additonal delay/flicker of the prevjew.

* Try?

* Format

* Update CameraSession.swift

* Use `defer`

* Throw `.device`
