Select source control based on actual setup/connections when starting comparison
When starting a comparison and selecting source/target environments for Source Control - it shows all connection types including those that I haven't connected.
With browser cache, it seems to remember the one you selected last. However, for new users (or when you clear cache) it'd be ideal if Gearset would default your source control on this screen to whatever the user has connected. Once a user has connected a source, there's no sense in having the user choose it again at this step.
