I did all my best to remove all the parameters during move or delete (I have unset all the known parameters) but if there was still one parameter still there (even not any more supported), when the remotes are read, an invalid remote is returned whithout datas :(
To prevent that, I filter invalid remotes.

PS :For the moment unset all the parameters througth libgit2sharp, let the line `[tfs-remote "test_branch"]` in the config file. It's not a problem and they are now aware of the problem!
