[FIX] base: put parsing of an email 'from' into a try except block

The "from" of an email is expected to follow the regex
"name <address>(, name <address>)*".
We simply split the from on the commas "," and try to interpret each piece as a
(name, address) pair.
If a "from" contains a name that is not quoted, and contains special characters
before the comma, then we would try to encode that name into an email address,
and fail on a UnicodeEncodeError.

E.g. the following "🐧, <a@a.com>" would be parsed as [('', '🐧'),('', 'a@a.com')]
thus Odoo would crash on trying to use 🐧 as email address.

With this commit we would just mess up the name in these situations,
by ignoring failures.
