* [ACS-4130] Resolved issues related to editing existing rules with 'Has Category' condition

* [ACS-4130] Added safety checks and minor code refactoring

* [ACS-4130] Added unit tests for new autocomplete functionality

* [ACS-4130] Added feature to auto select first option from autocomplete dropdown when user focuses out of autocomplete input field

* [ACS-4130] Minor code refactoring. Moved constants from global scope to local scope

* [ACS-4130] Moved mock data to conditions.mock.ts. Removed redundant return type

* [ACS-4130] Resolved PR review comments - AutoCompleteOption is now an interface. Changed occurences of autocomplete with auto-complete. Removed/Added types

* [ACS-4130] Resolved PR review comments - AutoCompleteOption is now built using a single common helper method

* [ACS-4130] Added missed types
