roomservice: Follow fetched android_device_ projects

* In a situation where the Android tree is already
    fetched and entirely set for a device tree,
    all additions to cm.dependencies in a common
    project were ignored due to being already fetched

 * Add a new array of projects to verify but not
    necessarily fetch, and fill it upon fetch request
    or if the project starts with "android_device_",
    to let the iterations follow the common trees
