remoteSearch: Stop using callback to return loaded providers

Provider loading has been synchronous since 2013, so we can
just as well return the results directly instead of passing
them to a callback.

Even if we returned to asynchronous loading in the future,
we wouldn't want to use a callback, but make the function
itself async.
