We can't change the order on ir.export.line since it's used to preserve the order speicifed by the user when creating a export filter into the UI

Sometimes you just want to turn off via configuration
lines created by some other modules.

If you use this module extensively - as I do -
you've done this tons of time. For sure :)
This little change simplifies your code base where needed.

…mple field

Before this change, the result of the export of a relational field was always a dict or a list of dict.

ex:

<record id="ir_exp_shopinvader_variant_lang" model="ir.exports.line">
  <field name="name">publication_language_id/name</field>
  <field name="alias">publication_language_id/name:lang</field>
  <field name="export_id" ref="shopinvader.ir_exp_shopinvader_variant" />
</record>

will output:
{
    ...
    "publication_language_id" : {
        "lang": "French"
    }
    ...
}

After this change it's now possible to define simple exporter for relational fields where the value into the result will be the display_name or a list of display_name of the related records.

ex:

<record id="ir_exp_shopinvader_variant_lang" model="ir.exports.line">
  <field name="name">publication_language_id</field>
  <field name="alias">publication_language_id:lang</field>
  <field name="export_id" ref="shopinvader.ir_exp_shopinvader_variant" />
</record>

will output:
{
    "lang": "French"
}

(Cherry-pick of 652c016 after this commit was dropped by #1894's refactoring)
(+ test so that it cannot be forgotten again)

It could happen that a module adds an ir.export.line for a new field
but when tests run the field is not loaded
if this module is not a dependency of the module running tests.

Furthermore, in general, it seems too strict to break the whole computation
if there's a field that is missing.
It seems more reasonable to log an error when this happen
so that technical action can be taken to fix it.
