portal's tests set an invalid email address, `c@c`, that's rejected
by the current version of partner_email_check. If partner_email_check
is installed before portal's tests run then they fail.
To solve this, skip email validation if tests are running, unless a
key in the context is set to make the checks run anyway. That lets
tests in other addons opt in to the checks as well.
The previous update to partner_email_check didn't bump the version
number, so do that now.
