Command library canvas app (.msapp) filename is different for every solution export

When exporting a solution containing a command library canvas app the app name is different on each export. This creates noisy diffs and bloats source control.

To reproduce:

1. Publish all via pac solution publish --async
2. Export solution with pac solution export --name $soln --path $zipfname --async
3. Unpack solution `pac solution unpack --zipfile "$zipfname" --folder "$solutionfolder" --packagetype $packageType --errorlevel Warning --allowDelete true --processCanvasApps
4. Repeat steps 2 and 3

Note it does not matter if Unmanaged or Both packageTypes, or if --processCanvasApps is omitted (and a later pac canvas unpack is used)
