Bug 925961 - [B2G][Email] Receiver's email address displays as "null" after saving, editing, and then saving the draft again

Hi Andrew, James,

The patch is just the same as https://github.com/mozilla-b2g/gaia/pull/13028/commits.
And the 13028 PR was already r+, so you guys could just check this patch works well in v1.2 or not.
Thanks.
