Fix query being cleared when hideOnChosen is false (#74)

* Fix query being cleared when hideOnChosen is false

If the hideOnChosen behavior is turned off, we do not want to clear the typeahead query. 
This lets users select or deselect options from within the suggestions list, without forcing
the list to be reset with every choice.

* Update version to 0.7.0
