Calendar resets `tab` query param after returning back from other page

[trakhimenok]

To reproduce:

• Go to space calendar page - day tab should be selected by default
• Select week tab
• Select day tab
• Click on a day item [Add recurring]
• On new happening back click in top [back] button
• Problems:
  • Check URL - the tab parameter either removed or has week value instead of expected day value.
  • If no parameter in the URL then the URL does not change anymore on tab change
