chore(storage-browser): Clean up control prop forwarding

[cshfang]

Description of changes

This PR cleans up controls to no longer render null but instead pass down default (empty) values for props. This allows the composable component to make the decision of what it should do rather than simply cutting off that decision point at the control level.
