[PATCH] Ensure that loop always receives an array even if only one series

[Mike Crowe]

Similar to fee90b0f902a75d87022f91ef7978b17cfa00625, this fixes a
runtime error on pid b01d8jmz:

INFO: Brand pid detected
INFO:  Brand: 'Dirk Gently' (b01d8jmz)
Not an ARRAY reference at ./get_iplayer line 5622.
