refactor: use a regular action for 'resetRoot'

Previously, 'resetRoot' directly performed a 'setState' on the container instead of dispatching an action. This meant that hooks such as listener for 'preventRemove' won't be notified by it. This commit changes it to dispatch a regular 'RESET' action which will behave the same as other actions.
