[PATCH v4 1/4] test: add `notmuch-hello-mode-hook-counter'

[Dmitry Kurochkin]

Add `notmuch-hello-mode-hook-counter' hook to count how many times
`notmuch-hello-mode-hook' was called.  The counter function increments
`notmuch-hello-mode-hook-counter' variable value if it is bount,
otherwise it does nothing.
