Fix trashcan icon

[kmur911]

Currently the trashcan for deleting api keys/identity providers doesn't work. However I'm also curious why you should be able to delete your identity provider if you only have one and that was the way you registered. In that case, if you deleted your Google oath connection for example wouldn't the account become unusable, as you have no other password? Might make sense to hide the trashcan if you're down to one provider and don't have a password.
