Rémy Voet (ryv) d982c4f319 [IMP] core: save one query when reading one2many on a single record
For reading one2many fields, we make 2 queries (in batch):
- One to search "id" the comodel
- One to read <inverse_field> in the comodel to group lines by record
(sometimes, this one is bypass because the cache already contains the information).

In many cases (> 80% of cases in our tests) we read a one2many field on
a single record.  In that case, we can avoid the second query completely
(grouping all lines on a single record is trivial).

This reduces SQL queries by about 0.8% on all-install runbot builds.
