SameNugetPackages rule ignores Analyzers

[imanushin]

Rule ignored packages, which are added without package.config change. For example, analyzers can be added by following tag into csproj:

  <ItemGroup>
    <Analyzer Include="..\..\..\solutions\packages\VSDiagnostics.1.9.4\analyzers\dotnet\cs\VSDiagnostics.dll" />
  </ItemGroup>

Target rule should union these lines with packages.config dependencies
