[PATCH] notmuch.c: add missing trailing newlines in two error messages

[Tomi Ollila <tomi.ollila@iki.fi>]

Removed duplicate error check (and the message) in 3rd case where
the same error message (w/o trailing newline) was present.

In case of test/T040-setup.sh, command substitution deletes
trailing newlines, so related test there cannot be changed
(and therefore could not notice this user experience flaw).
---

The current error message can be experienced with

$ NOTMUCH_CONFIG=no-cnfig-thre notmuch new
    and (the second change, removed in this commit)
$ NOTMUCH_CONFIG=no-cnfig-thre notmuch config
