Trim TreeBranchEvents

[noencke]

This removes events on tree branches that are specific to views. This is part of ongoing effort to expose branches as separate entities from views. This is a breaking alpha API change - I will run the integration pipeline to ensure compatibility. Use hasRootSchema to get the view from your branch if you want to use the events that were removed.

• Integration Pipeline Succeeded (FF Build 385127)
