When 80f1ac3599 removed deferral of
parent store computations (the MPTT at the time), it also errornously
removed the computation during auto_init.
As a result, when adding a `_parent_store = True` and `parent_path`
field to an existing model (e.g. in an override, or when updating the
database) the column will be created but the column will be
False-filled, and hierarchical queries break as odoo will attempt to
perform string operations on `False` (either `False + '%'` or
`False.split('/')`).
Fix the issue by reintroducing the parent_store computation.
Note: uses the same gating as the old commit, the computation is only
performed if this is the install/update where the parent_path column
gets created.
We could alternatively gate on just _parent_store, but even the RCTE
can be expensive when executed on millions of records (at least when
it has to set all the parent_path) and while it could allow inserting
a bunch of records when calling -u to generate their parent_paths, it
feels like the caller could and would do so manually as they might
have shuffled the tree and need to update more than just the records
for which parent_path is null.
