emacs: Fix `notmuch-show-rewind' in the presence of invisible text

When determining whether or not to re-align the head of the current
message with the top of the window, use `count-screen-lines' rather
than `count-lines' to allow for invisible text in the preceding
message. When comparing that number of lines against
`next-screen-context-lines', realign if the number of lines of the
previous message visible is 'smaller than or equal to' rather than
just 'smaller than' to improve usability.
