UX Feedback patch

After talking with UX I've made this PR in order to adapt our code to this requirements:
- Restore 'action-menu' behaviour. Clicking/Tapping on it means 'hiding' it.*
- There is no mechanism for keeping the 'action-menu' due to (*)
- Adding new String for email (because I dont know if we are going to use in the future)
- Removing 'call' option from 'secondary-menu'. This means that we are not going to repeat the main action in the 'action-menu' (same for email).

That's all! Please merge it, squash and add reviewer name and I will review again!
