[FIX][base_export_manager] Fix "Expected singleton" bug.
If you had a field that got translated in more than 1 addon, you'd possibly getto this error:
File "/opt/odoo/0079_ahk_openerp/oca/base_export_manager/models/ir_exports_line.py", line 105, in _compute_label
field.name)),
File "/opt/odoo/common/openerp/v8/openerp/fields.py", line 825, in __get__
record.ensure_one()
File "/opt/odoo/common/openerp/v8/openerp/models.py", line 5355, in ensure_one
raise except_orm("ValueError", "Expected singleton: %s" % self)
except_orm: ('ValueError', 'Expected singleton: ir.translation(4899, 703976)')
With this patch, now we let Odoo return the translated string by using its
standard method to do so, so we have to care for less.
* Move installation outside a data file.
This makes the whole installation to be able to roll back if something goes
wrong, instead of entering an error loop.
* Include envorionment in its manager.
* Add 4th field
* Move to api.multi, refactoring some stuff.
- Add some comments in complex parts.
- Rename `onchange_name` to `_onchange_name` (guidelines).
- Make `_compute_name`'s try block shorter and easier to understand.
* Allow R/W of name directly in model.
* Update tests to cover new behaviors.
