Comments: Don't do direct SQL query when fetching decendants.

The SQL query was built using the clauses compiled when querying for
top-level comments. But in cases where the top-level comment query
results are already in the cache, the SQL clauses are not built, and
so are unavailable for `fill_descendants()`. Instead, we call
`get_comments()`, using modified versions of the parameters passed
to the main `WP_Comment_Query` class.

Props Akeif, Rarst for testing.
Fixes #37696.
Built from https://develop.svn.wordpress.org/trunk@38446
