[PATCH v2 8/8] emacs: Remove interactive behavior of `notmuch-tag'

[Austin Clements]

We no longer use this, since we've lifted all interactive behavior to
the appropriate interactive entry points.  Because of this,
`notmuch-tag' also no longer needs to return the tag changes list,
since the caller always passes it in.
