Bug 11067: fix some issues with the PNP launch wizard
1) If Sys TRK is detected, and you select to install a package, a Sys TRK launch is created
2) Error message was confusing when Carbide chose to install a package but SIS configuration was not complete.
3) In an internal layout, assume Sys TRK is more likely than App TRK if we cannot tell from the connection.
