Delete stale files with PushChangedFiles and install all fake module apk

Pass delete_device_stale=True parameter to PushChangedFiles to properly
remove previously installed apks from device.
Only remove apks that don't match any fake modules from path being
pushed to device so that script supports installing multiple fake
modules at the same time.
