Default total count true for get-records-by-query

[saitouena]

Rationale

before:

(-> (<!! (record/get-records-by-query conn app {:total-count true}))
     :res
     :totalCount)

It requires kebab-case keyword but returns with camelCase keyword. This is confusing.
after:

(-> (<!! (record/get-records-by-query conn app))
     :res
     :totalCount)

This situation only happens in get-records-by-query for now. To set totalCount: true makes it easy.

Note for kebab-case and camelCase is also added.
