Fix sync settings sometimes opening upon restoring Android device backup

The linked bug has more context. To help with terminology, say that a
Chrome version is "new" if it contains this commit, and "old" otherwise.
Also say that a "backed up" device is one whose data was uploaded, and a
"fresh" device is one restoring the data. This CL has 2 effects:
- If the backed up device had a new Chrome version, sync settings will
not open on restore, regardless of the version in the fresh device.
- If the fresh device has a new Chrome version, sync settings will not
open on restore, regardless of the version in the backed up device.
