chore(react-tag-picker): ensure no toggle behaviour when re-selecting already selected data

[bsunderhus]

Previous Behavior

At the moment whenever the user tries to re-select the same option, the option is unselected. This happens because we're using Combobox logic internally to implement TagPicker logic, but this is a bit problematic in this scenario as Combobox supports toggling the selected data on the "option select event", meanwhile TagPicker only allows selection on the "option select event", to unselect a tag should be clicked manually, it does not involve the combobox logic

New Behavior

1. adds conditional logic to ensure internal combobox state will not be updated in this scenario. Instead, onOptionsSelect should be invoked with the current selectedOptions with no modifications
