FI-2270: Migrate FI-1990, fix flicker

[AlyssaWang]

Summary

Prevent components from rendering until suite options, waiting test ID, and selection panel width are loaded in. Fixes flickering on new test session creation.

Testing Guidance

1. From inside a session in a suite with no options, start a new session by clicking the header. The new session should start with no intermediate flickering.

2. Repeat but with a suite with options. The screen should display without the description changing width. Try with small screen and large screen.

Walked through the recommended test steps and it worked as expected in firefox.
