[NuGet] Allow package reinstall when other packages depend on it.

Forcefully uninstall a NuGet package to make sure the uninstall does
not fail when other NuGet packages depend on the package being
uninstalled.

For example, Ninject and Ninject.Extensions.Xml installed into a
project that targets .NET 4.0. Ninject.Extensions.Xml depends on
Ninject. Trying to remove Ninject will fail but reinstalling Ninject
should succeed.
[NuGet] Reformat Package Console output from compatibility check.

Add new line between incompatible NuGet packages message and the
list of NuGet packages.
