[web] Move currentTabType state up from ThreadSettingsModal to ConnectedThreadSettingsModal
Summary:
Move currentTabType state out of the inner class component state, and move it out to the wrapping "Connected" functional component.
As part of the work to refactor ThreadSettingsModal… specifically to turn it into a functional component.
Depends on D3757
Test Plan:
Close reading... should be a noop
Will test the entirety of ThreadSettingsModal thoroughly once the refactor is complete (plan on using this as an opportunity to write some automated tests)
