Unending UIActivityIndicator loading bug fix.

Scenario:
1. Open application.
2. Go to settings while indicator is spinning.
3. Go back.

Expected:
Activity indicator disappears after loading all necessary information.

Actual:
Application adds one more instance of UIActivityIndicator, that never
ends.

By fixing this bug I have decided to add an ivar, that will contain
previous server data and compare it with new one. That will also remove
unnecessary server call if jurisdiction isn't changed.
