[FIX] web: use correct domain when fetching status values

The m2o choices that a status field works with are determined using the
associated domain. If the current value is not matched by this domain,
the current value should still be visible so the domain is
automatically extended to match this current value. The problem is that
the current value in edit mode or in create mode is not given by the
`data` attribute of the associated datapoint. Indeed, user changes and
default get are stored in the `_changes` key and it is those values
that must be used if they exist.
