Move idOfView and idOfModel utility functions to go.utils
Add custom parsing to ConnectionModel to set connection uuid from the source and target endpoint's uuids
Removed unnecessary event callback from ConnectionView test beforeEach()
Added a 'parse: true' option to StateMachineModel's 'connections' relation, and similarly for CampaignRoutingModel and DialogueModel. This ensures that the connection models are parsed (and given ids) before Backbone-relational tries find or create the models.
Added a test to CampaignRoutingModel to ensure duplicate routing entries aren't made on successive calls to fetch()
Merge branch 'develop-frontend' into feature/issue-388-connectionmodel-needs-custom-parsing-to-set-connection-uuids
