[IMP] base: prefetch the properties definition

Purpose
=======
Most of the time we will need to read some field on the definition
record when we read the record itself (e.g. fetching some project
information on a task).

Because of this, it makes sense to prefetch by default the properties
definition, and it reduces the number of queries as well.
