Remove blank lines at the end of project files

[icnocop]

Hi.

Thank you for migrateToAutomaticPackageRestore.ps1.

I would like to request that blank lines at the end of project files be removed.

They weren't there before Enabling NuGet Package Restore on the solution, and so they shouldn't be there when running migrateToAutomaticPackageRestore.ps1.

Thank you.
