Bug with nuget creation

[tsibelman]

I encountered following issue that looks serious to me.
paket.exe pack add pdb files in regular nugget packages. Nuget.exe includes them only in *.symbol.nuget packages.

Adding pdb files in regular nuggets makes it impossible to get correct sources while debugging

@forki Did you saw this issue ?

Is it related ? Here I talking about regular nuggets including pdb file while they should not.
