No more error when doing the update_relations.

Couple things I noticed:

1. If a cam has no weather nearby it just does the loading animation (https://dev.drivebc.ca/cameras/970)
2. If you go from one cam to another, and lets say cam A had a weather station linked to it, but cam B did not, then it will keep showing the weather from cam A. When you eventually pick a cam that does have weather linked to it, it will update.
