Subject: Reset selection on DataProvider change in RadioButtonGroup (#11526)

* Reset selection on DataProvider change in RadioButtonGroup

Fixes #11454

Other components needing the same fix are ListSelect,NativeSelect,Combobox (The ones implementing HasDataProvider and extending AbstractSingleSelect. Grid is not affected as it extends AbstractListing and hadles selection differently)

* Added test case

Verify that ValueChangeListener is actually fired after value is reset setting new DataProvider
