Fix segmentation fault when exporting ical file
If a note file gets accidently deleted this leads to ical_export_note trying to execute fclose(NULL) which leads to a segmentation fault on current Debian GNU/Linux using libc6 (according to fclose's manpage, the behaviour is undefined in this case). The fix tests whether fopen returned a non-NULL-pointer before trying to close it. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
