Up to this revision, barcodes set in reports are generated
using the controller `/report/barcode`,
using a `img` HTML tag, e.g. (from `report_location_barcode`)
```
<img t-if="not o.loc_barcode"
t-att-src="'/report/barcode/?type=%s&value=%s&width=%s&height=%s'
% ('Code128', o.name, 600, 100)" style="width:300px;height:50px"/>

This `/report/barcode` route is set as `auth='user'`, meaning
the route can only be accessed by signed in users.
When wkhtmltopdf prints a report containing such a barcode,
it calls this `report/barcode` route, making sure to pass
the request session in the cookies, so wkhtmltopdf
uses the same session than the one of the user. This is
needed, as only users can access this `report/barcode/` route.
This session is passed in `report.py`, in the method
`_run_wkhtmltopdf`, thanks to the --cookie wkhtmltopdf
parameter.
Nevertheless, if a report is printed through the website
front-end, as public (without a signed in user), the request
session is not associated to a signed in user, and therefore
the route `/report/barcode` refuses the access / redirects
to the login, making it impossible to print a report
containing a barcode without being signed in. This even
if the report is printed as `sudo` through a controller
(as this is the session of the not signed in user which is passed,
not a session associated to `sudo).

In the website editor, the translations are loaded using
the route 'get_view_translations', which returns the translations
of the templates loaded by the website (t-call calls)
The thing is, report templates use the 'translate_doc' method
to actually load the report, translated in the partner language,
and the templates loaded by this method are not seen by the website,
therefore, when calling 'get_view_translations', those report
templates were just ignored, thus their translations are not loaded.
This rev. injects the templates loaded with translate_doc
when rendering the report into the method 'customize_template_get'
(which is used by 'get_view_translations' to retrieve the loaded templates).
The translations of the reports are therefore now loaded corretly when
hitting the "translate" button in the website editor for reports.
Besides, this rev. has as (good) side-effect to add the template,
in the template selection input when editing using the HTML editor.
