Empty envelope search result leads to page 1 out of bounds error

[echo-bravo-yahoo]

Hey - I'm using himalaya with gmail, and am trying to find unread emails in a folder. If there are any unread emails, it works great - but if there are 0, it fails with the error 0: cannot list imap envelopes: page 1 out of bounds. The CLI command looks like the below; let me know if trace logs would be more useful than debug logs.

> himalaya envelope list -f "Jobs" --page-size 10 --debug not flag Seen

Looking at the (possibly related) #518, I also tried with an explicitly 0 page size:

Indeed, nice catch! It should return an empty table instead. I will fix this for the next patch release.
