UI: Fix outdated scene collection and profile method names

[PatTheMav]

Description

Fixes method names for certain scene collection and frontend methods exposed via the frontend API that had been renamed during review phase of #11055.

Motivation and Context

Restores functionality of the corresponding frontend API methods.

[!NOTE]

Plugins which invoke public slot functions on the UI thread directly instead of using the frontend API will face the same issue. Luckily this should not result in crashes or other issues at runtime as Qt will just ignore the call and at worst post a log message about a non-existing method being invoked.

How Has This Been Tested?

Tested with a simple plugin that invokes the corresponding frontend API functions.
