DO NOT MERGE Fix other String.format issues in NetworkNotificationManager.java

Commit fb2609d3eee1c7a4dda889c000f32183a044978a added a string
format which caused an exception.  On top of the fixes to this
from e1406167186c2cabe683b3c1511ad6733e9106c9, we can also fix
a few more issues here with some missing arguments to other
String.format invocations in the aforementioned CL, and other
formatting problems.
