Remove shims that call super

They were previously there for documentation purposes, but we've decided
to document them in the text-buffer npm directly and link it into the
documentation. This drops some of the docs on delegated methods, because
our docs generator doesn't understand `delegatesMethods` declarations,
but TextBuffer was marked private anyway so we can get back to it later.
