fix: url initialization flag sequencing

[briangregoryholmes]

Fixes an issue where the URL initialization flag was set prior to certain stores being initialized. The side effect was that the range store would briefly be set with a default value even when one was present in the URL, though this would only happen on canvases referencing more than one metrics views.
