Add unique constraint to email branding domains Does two things: 1. Revert "Revert "Add unique constraint to email branding domain"" This reverts commit af9cb30ef30fe3859507a5747a65255b7466af4b. 2. Don’t allow empty string in email branding domain Columns with multiple `null`s can have a uniqueness constraint. Columns with multiple empty string values are not considered unique. This commit: - removes any duplicate empty string values - casts empty strings to null string any time these columns are updated --- Squashed into this single commits because these two things are not atomic as individual commits. 2018-09-04 10:57:47 +01:00			`"""`
