Don't create adb client during module import
Don't create adb client during module import

Summary:
Creation of the adb client requires the logger to already be initialized, so this should never be called at the global scope in a module, or you'll get weird import-order related bugs.

I noticed this while debugging, I don't think it's impacting anything right now, but have made it lazy just to avoid confusion in future.
