Correctly get uids for per-app network preferences

Browse Source 
Per-app network functionality assumed all apps were installed for user 0
which is not always the case. This fix will address that by checking for
the existance of an app for all users and adding it to the per-app
network preference as was originally intended. Prior, no apps were
included if they were not installed for user 0 even if they were
available for another user such as user 10 in automotive.
