Hello,

Currently denote-rename-file-using-front-matter is failing when there
are no keywords on the front-matter, even if the filename is computed
correctly without them.

I coincidentally came across this email today, which had the same exact
issue but with the signature:

https://lists.sr.ht/~protesilaos/denote/%3C87zg86lru9.fsf%40kotlak.com%3E

I based my change on that fix, let me know if that's OK.

Thanks for the great project!

Keywords are optional, and the filename is computed properly when
they are nil.
