Drafts without dates not rendering correctly about jekyll-algolia

[leviem1]

Turns out not including a date in a non-draft post is handled gracefully. There may be some clues there as to how we can avoid this issue, as long as the behavior isn't "just ignore it", since that'd make the drafts invisible again.

Jekyll doesn't require dates for drafts to be rendered, so it would be a bit jarring to force users to start dating their drafts.

Thanks for suggesting a change. I'm personally more in favour of catching this error and giving a clearer error on where to add a date.

How does it behave for non-draft posts without date?

Hey, just checking in on whether or not you've seen my PR. I assume you're busy so I understand if it's lower priority, but wanted to make sure this didn't fall off the radar.

Thanks for everything!

I've released this under 1.7.1, thanks for the PR!
