display: do not try to draw content when there is no open buffer yet

Browse Source 
Commit b63c90bf avoided creating an empty buffer before asking the
yes-no question when encountering a lock file at startup, but the
SIGWINCH code still expected to have an open buffer whose contents
to show.

This fix also has the pleasant effect that, when resizing the screen
at the lock-file yes-no prompt, the title bar doesn't suddenly appear.

This fixes https://savannah.gnu.org/bugs/?58414.
