Back navigating from agenda to month view

[andrehgdias]

After navigating from month to agenda view, allow navigating back to the previous view.

AC

• After navigating from month to agenda view there is a back button in the top left corner which navigates to the month view. (iOS and Android)
• The hamburger menu is not available in this case
• In case the user selects agenda view from the view selector the hamburger menu is visible.

Test Notes

• When navigating to Agenda view from Months View, there's a back button instead of the hamburger menu
• The back button returns to Months View even if we change the date in the Agenda View
• If the user uses the view dropdown to go to agenda view, there's no back button and the hamburger menu is visible

Regression Test:

• When viewing an email, there's a back button that returns to mail list
• When viewing a contact, there's a back button that returns to contact list
