term: cursor_refresh(): don't try to dirty the grid if we don't have one

Browse source 
If the compositor sends a keyboard enter event before our window has
been mapped, foot crashes; the enter event triggers a cursor
refresh (hollow -> non-hollow block cursor), which crashes since we
haven't yet allocated a grid.

Fix by no-op:ing the refresh if the window hasn't been configured yet.

Closes #1910
