[FIX] ir_actions_report: Render correctly the base64 images in P3

Purpose
=======

In python2 a binary field value is retrieved as a string. Example: company_id.logo = u'xyz'

In python3 a binary field value is retrieved as a binary. Example: company_id.logo = b'xyz'

When trying to render an image on a template, we should pass a stringified version of it.

Specification
=============

Pass the method to_text in the template rendering context and use it.
