Back button doesn't work after completeting action from camapign

[JElgar]

Steps to reproduce:

• Go to a campaign which contains actions (not learning)
• Click on the action
• Mark the action as complete
• Close the popup
• Click the back button at the top of the page (do not use native swipe to go back) - This should take you back to the campaign
• Then click the back button at the top of the campaigns page (again not native swipe to go back) - This should take you back to the action
• You will now be stuck in a loop (if using those on screen buttons)
