Display the caption of the Empty selection in NativeSelect (#11191)
* Fixes #10937
- Previously if selected value is null, then index is set to -1; in current implementation if value is null and emptySelection is allowed then set the index to 0. (The position for the empty selection)
- Also, if changing the allowEmptySelection on the fly, ensure, that either index is to-reset to -1 by setting the selected value to null on the client-side (the value before was null) or preserve the value(value was different than empty).
* Change the test case
Since in this pr the behaviour of the NS is changed, therefore old test need to be adjusted.
Change: setting null as value will select empty selection. Before that nothing would be selected and value will be cleared.
Behaviour change in PR: Allow selecting null as value
