V3 of notmuch-show-message-resend feature

v2: id:1441204482-26509-3-git-send-email-tomi.ollila@iki.fi

id:87pozza0dw.fsf@qmul.ac.uk has been consulted while doing
these changes (iirc ;)

I tried to get company mode also work while reading email
addresses from minibuffer -- and got something to function,
but not anything really working. Therefore this currently
uses minibuffer (with tab completion) working.

The following diff shows what I tried to do to get it working.
In addition to work poorly it breaks "normal" address tab
completion (as it was crafted to work with minibuffer completion
tests only)
