Fix monthly clones

[Mattchewone]

When cloning a month into a new month, we should not be cloning the intermediate model _id's as this prevents the #each loop from updating as the "key" or "identity" isn't changing when the list changes.

• We need a script to go through and create new id's for each of the records.
• Put back the identity prop on the intermediate models
• Fix cloning mechanism to strip any id's
