Pins created by locate place/address main stage action do not disappear.

[oevans]

Location pins will stay on the map if the [ < BACK ] button is not clicked between activating main stage actions to locate an address or place.

Steps to reproduce:

1. Configure two or more main stage actions to locate an address or place.
2. View the map journal in view or builder mode
3. Click the text of one of the main stage actions. Map will navigate to the location and drop a pin on the map.
4. Click the text of another main stage action (without clicking the BACK button at the top of the main stage). Map will navigate to the location and drop a pin and the first pin will still be visible.
