We're not properly concatenating the Received headers if we parse them
while requesting a header that isn't Received.
this fixes notmuch-reply address detection in a bunch of situations.
With this patch the Received: header becomes special in the way
we treat headers - this is the only header for which we concatenate
all the instances we find (instead of just returning the first one).
This will be used in the From guessing code for replies as we need to
be able to walk ALL of the Received: headers in a message to have a
good chance to guess which mailbox this email was delivered to.

fix notmuch_message_file_get_header to always return the first instance
of the header you are looking for

Calling continue here worked only because we set a flag before the
continue, and, check the flag at the beginning of the loop, and *then*
break. It's much more clear to just break in the first place.
