Overview
Fix a bug whereby the vector tile map would crash on logging in or
logging out caused by a missing check to ensure that the map object
existed before calling getZoom. Adjust it to use the stored zoom state
instead.
Connects #822
Notes
Fixing this uncovered another quirk whereby we are clearing the existing facilities data on logout, along with the filter settings. This is how the existing map setup also works, so I did not try to address it here and will make another card for fixing it.
