[5.x] Warm structure trees during static warm

[jasonvarga]

There's an issue where if you run static:warm immediately after a cache clear, entries from a structured collection will 404.

This is because mid-query for entries, the uri indexes get built (as expected) but for structured entries their uris come from their structures. As part of that, the trees are validated, which also queries the same entries, which don't have uri yet. The uris get indexed as nulls, and therefore will 404 when they are searched for later.

Or, something close to that. 😅

This PR is really a workaround, but seems to resolve it.

If you were to run stache:warm before static:warm, or if you visited any pages before running static:warm, you wouldn't have this issue.

This really sounds like it fixes the issue Lars describes in #10410. Or at least what I've noticed happing.

Sounds like it, but this PR is only concerned with static caching. #10410 isn't. 🤔

Yeah true, I think Lars and I are running into separate issues then. Cuz in my case I def. used full static caching.
