Reportgenerator: Release 4.8.6 does not produce accurate coverage reports for generic classes anymore

[rokeller]

As of the latest release of the global tool (4.8.6), reports generated for generic classes are no longer accurate.

Console output of ReportGenerator:
2021-03-04T10:59:40: Arguments
2021-03-04T10:59:40: -reports:D:\GitSrc1\common\Common.Data\Coverage\Temp*\coverage.cobertura.xml

2021-03-04T10:59:43: Report generation took 2.9 seconds

It looks like _all_ classes with generic type parameters are affected by this. However, the below minimal class and test easily show the problem too:

public class GenericClass<T>
{
    public string GetType()
    {
        return typeof(T).FullName;
    }
}

using Xunit;

public class GenericClassTests
{
    [Fact]
    public void ItWorks()
    {
        Assert.Equal("System.Int32", new GenericClass<int>().GetType());
    }
}

While the test does succeed and clearly covers the code, the generated report does report 0 uncovered lines, but also reports 0 covered lines which is clearly wrong.

Sorry for that.
I fixed it in release 4.8.7.
