User should be able to use any provider he has account with and therefore can have multiple active OpenID URLs (e.g. his homepage, Google account, Yahoo account, other wiki account and so on).
Right now OpenID extension only supports one active URL and overrides previous one which requires overriding back and forth if user alternates between using one OpenID provider and another (which is made easier with provider selector, bug 17631).
fixed in r52236.
