When a text fixture with arguments, has a test with a value containing a ".", only the part of the argument value after it will be shown in the modal dialog. This is due to the "namespace-trimming" on https://github.com/JatechUK/NUnit-HTML-Report-Generator/blob/master/NUnit%20HTML%20Report%20Generator/Program.cs#L398 Since at other places the namespace is know, it should be used here as well.
