Change LocalUser sql model to eager loading
This patch changes the LocalUser sql model to eager loading. Subquery
loading is eager loading as the parents are loaded, using one additional
SQL statement, which issues a JOIN to a subquery of the original
statement, for each collection requested.
Closes-Bug: 1606426
