How to fully delete Subclipse plugin?

I am having trouble getting rid of Subclipse from my Eclipse configuration.

I made the decision to switch to Subversive due to the m2eclipse project dropping support for Subclipse.

So I uninstalled Subclipse and then installed Subversive using the About Eclipse -> Installation Details -> Uninstall method. Now, when I go to any Team related options/tasks/preferences there are two SVN options available (one for Subversive and one for Subclipse) making life confusing.

Having grepped the workspace .metadata folder for the string subclipse I can see that the configuration is still littered with references to Subclipse:
