WPB-25247

Issue

This PR allows guests to access conversations shared drives even if they're on a team with drive disabled.
Also added UI test.

Testing

• Have userA on drive enabled team
• Have userB from another team (drive disabled)
• Connect both users
• UserA creates a drive enabled group conv with userB
• UserB should have access to shared drive on this group conv (drive tab should not show though)
