[FIX] models: avoid Unicode error when translating that error message

The patch fa492d87f42f97d05ba93255a77e24c35158fe62 has been backported
from Odoo 12.0, that runs on Python 3.

The string '\n\n({} {}, {} {})' to be formatted is a byte-string in
Python 2, while the return value of _() is always a unicode-string.

As format() is (too?) nice, it attempts to convert the unicode-strings
into ascii in order to inject them in the format pattern.
With some languages that are written in ascii, this works -- by chance.
When you use non-ascii languages like Japanese, it fails.

We then fix that issue by using unicode-strings in the formatting
pattern.
