Duplicate WebhookHistory records if multiple builds are started?

[praiskup]

Per:

copr/frontend/coprs_frontend/coprs/models.py

Lines 1601 to 1605 in 1685748

	id = db.Column(db.Integer, primary_key=True)
	created_on = db.Column(db.Integer, nullable=True)
	# Null values are possible via custom webhook implementation that do not pass a UUID or User Agent.
	user_agent = db.Column(db.Text,nullable=True)
	webhook_uuid = db.Column(db.Text, nullable=True)

And #3456, it seems that when one webhook triggers multiple builds, we get multiple WebhookHistory entries.
