Configuration Fixes

[InTheCloudDan]

• Configuration update was not properly awaiting
• Configuration should return early if there's no accessToken configured
• Hover should return early if there's no environment. We may want to remove the console.log of the error as it's not unexpected if not configured but I left in there for now.
