Updates service selection functionality to always re-run volume query on activation of service selection scene.
This bug was likely introduced with the runtime datasource change.
Ideally there would be a way to know if a dataprovider has changed datasources, and we could only re-run this query when the datasource changed, and otherwise use the cached result if available, but this appears to be a consequence of using a runtime datasource.
