dev/core#150 : Chain select for country/state in Search Builder does not stay within OR groupings

[monishdeb]

Overview

This PR fixes two issues:

1. Upon chain select for country/state affects the list of respective states/counties select field of different "Also include contacts where" sections.
2. If no states/counties are present in the respective selection of country/state then it wipes out the list of these select fields.

I just tested this locally & can confirm I could replicate the bug & it being fixed. Code is restricted to form presentation layer so I feel that it is low risk outside this replication

Thanks @eileenmcnaughton
