Put name and num params in same log chunk (#11451)

[SAKavli]

We wish to query for entries which have logged both the experiment type and num params. However, if logs gets too long, they get divided into chunks, which might separate experiment type and num params into different log chunks, which complicates the query logic.

This change will ensure the first chunk will always contain both of these properties.
