Map icons flashing and stuck

[AWKevin]

I was on a run page (Nolichucky) and then clicked map at the bottom to see all the runs in the area. the icons for all the runs pulse/flash in roughly 1-second increments and clicking one will open the river name icon for 1-second and then it closes.

Replicated: Go to a run, go to the map for that run (top of page map option), then click on Map at the bottom of the page.

This is related to the location distance updates. Not sure why it's updating the map though.

@Gregliest I took a quick look at this, looks like DefaultsManager.shared.lastDistanceCoordinate doesn't get updated when reach distances get set, so distances update every time the map's user location updates.

@yeahphil Yes, see #266
