frontend: Don't reload scene collection after rename

[Dankirk]

Description

Skip unnecessary scene collection reload during rename for better ux.

Motivation and Context

The goal is better user experience. For example the reload after renaming caused active audio/video files to reset to beginning.

As a side effect this also works around a hang issue described in #13495, since the reload is skipped. The underlying issue should still be addressed, but is outside of this pr scope.

How Has This Been Tested?

After renaming I monitored the scene collection is handled as should while switching scenes, collections, interacting with sources and restarting app.
