** Forward Port from 9.0

* [FIX] Fixed the res.users view

The string attribute should not be used as a selector, because it is
translatable.

* [FIX] Fixed the print_document method of report

The new API migration was made to @api.multi because of the "cr, uid,
ids" signature, but "ids" was the ids of the records to print here, not
the report's ids.
Also, the new API version of "get_pdf" get directly the ids of the
records to print in the standard module, not a recordset.

* [FIX] UI is now (un)blocked only when using qweb-pdf reports in standard addons
