Make ‘Too many recipients’ error lower priority

This commit makes two main changes to what happens when a user is
in trial mode and they upload some email addresses belonging to
other people.

1. Add a specific banner error telling the user about trial mode

2. Make this error higher priority, eg it will show up before the
   error about having too many recipients in your file

This means making some changes to the tests so that the example CSV
files include the user’s phone number, then making them invalid by
omitting data required by the templates.

Depends on: https://github.com/alphagov/notifications-utils/pull/34
