[devtools] Throw adding 2 internal authenticators

Have devtools throw an error when a client attempts to add an internal
authenticator when there's one already present in the environment. This
is not supported and causes all sorts of issues.

This requires fixing a WPT that did not clean the virtual
authenticator. The WPT passing and not crashing Chrome previously was
luck.
