Restore version throws exception without NXTag facet

Scenario:

Define a versioning policy to create major version on blob update, minor version on metadata update.

Define a doctype without the NXTag facet e.g. MyDocType

Deploy.

Create a document (version should be 1.0)

Upload new blob (version should be 2.0)

Restore version 1.0 over 2.0

Expected Result:

Get document version 3.0

Actual Result:

Get version 2.0+ (but this is not the issue relevant to this ticket)

Get error in server.log (see full stack trace attached)

[org.nuxeo.ecm.core.work.AbstractWork] Exception during work: ListenerWork(Listener taggedVersionListener [documentRestored/3a74bea6-bb8c-4990-afe0-27cf6e8f6cc5], Progress(?%, ?/0), null)
org.nuxeo.ecm.core.api.NuxeoException: Document DocumentModelImpl(3a74bea6-bb8c-4990-afe0-27cf6e8f6cc5, path=/mydoc, title=mydoc) of type MyDocType doesn't have the NXTag facet

Workaround:

Add the NXTag facet to relevant doctype(s) (but not always suitable)

Note: the exception is still thrown if the NXTag facet is only applied dynamically to the document (i.e. not applied to the doctype)
