Bug 974867 - [MMS]Auto suggestion for email address r=Julien 

https://bugzilla.mozilla.org/show_bug.cgi?id=974867
please remove this

instead, add "isEmail: false" to the fixture.

Then add another fixture with an email as "number", "isEmail: true", and add tests about it (so with `Settings.supportEmailRecipient = true` for these tests)
