    Register ANDROID-APP image for pushing & pulling if and only if it has
    been set to something other than the default.

    This is work-around to an upstream issue with ANDROID-APP config. Briefly:
    User config is baked into ANDROID-APP builds, so Tutor cannot host a generic
    pre-built ANDROID-APP image. However, individual Tutor users may want/need to
    build and host their own ANDROID-APP image. So, as a compromise, we tell Tutor
    to push/pull the ANDROID-APP image if the user has customized it to anything
    other than the default image URL.
