Deduplicate actions by their look

1. Deduplicate actions by their look. Ideally, we should compare
   their labels and icons, but comparing icon is expensive and thus
    we are comparing title + component name instead.

2. Put intent to extras in ConversationAction object

3. Updated LabeledIntent.resolve, so we only support activity intent
   handler.

4. Fixed a minor issue in the browser title chooser.
   If it is resolves to sharesheet / chooser, we will still show the URL.
