Changed models visibility gets overriden initialViewState on ViewportComponent mount

[GintV]

Describe the bug

This is a regression comparing to iModel.js 2.19.x . We are using a viewportRef function property to get a reference to the ScreenViewport

After we do that, we adjust model visibility (add or remove models) by calling screenViewport.changeModelDisplay. After viewer is loaded, the adjustments we made are not present.

Looks like it happens because screenViewportRef.current?.changeView(initialViewState) is called one more time after line 279 was executed

Expected behavior After viewportRef function is called, view shouldn't be changed anymore on ViewportComponent mount.

Desktop (please complete the applicable information):

• OS: win 10
• Browser: chrome
• Version: 98.0.4758.141
• iTwin.js AppUI Version: 3.7.6
• iTwin.js Version: 3.7.6

This code was added to properly process the async method. It's not as simple as removing the additional call. I will look at this more next week.
