[FIX] web: BasicModel: don't mix fields and action contexts

The context sent when performing RPCs is a mix of several contexts
(user_context, action's context, context defined in a field's node
in an arch...).

In general, the action's context should not be mixed with the
field's context:
 - for global RPCs (read a record, write a record, default_get...)
   only the action's context should be given
 - for RPCs triggered by fields (e.g. name_search in a m2o), only
   the field's context should be sent.

The exception is for onchange RPCs, as in this case, both action
and field's contexts should be sent.

Before this rev, the action context was always sent, which might
produced tracebacks (e.g. go to Sales > My Pipeline > New > click
on Customer field > Create and Edit > boom).
