* Disable profile controls if the HS doesn't allow them to be set

Also updates to the js-sdk interface changes in https://github.com/matrix-org/matrix-js-sdk/pull/4246

* Remove unnecessary await

* Pass disabled prop to accessiblebutton in avatarsetting

* Use getCapabilities

in case there are no cached capabilities

* Fix test

* Go back to just using getCapabilities

Rather than change the other places
