Hi,
I have following error for migration but this error is completely unusual, because never i didn't have any code for add "RealmRoomMessage.messageId" to the migration. But i have many errors like this at fabric and unfortunately can't reproduce this state for make error.

Our project is open source and this is "Migration Class"

Unable to create application net.iGap.G: java.lang.IllegalStateException: 
Primary key property 'RealmRoomMessage.messageId' has duplicate values after migration.
