[FIX] web: deal with `can_create` and `can_write` option in M2O

The server postproccess the view to add attributes on many2one fields, i.e.
`can_create` and `can_write`, according to access rights.

These attributes are parsed by the client as string but should also be parsed by
the many2one when evaluating them.

The mock server has also been adapted to set these attributes.
