res/ari: Fix model validation for ChannelHold event

When the ChannelHold event was added, the 'musicclass' parameter was
erroneously removed. This caused the ChannelHold events to be rejected as
they failed model validation. This patch updates the Swagger schema such that
it now properly reflects the event that is being created.

Hooray for tests that catch things like this.
