Changes

Description=This is an equivalent call to the ‘classic’ one in UNIAPI, it will be used by GVP when receiving a GetUserRecommendations request from a ‘legacy’ device.

One important feature for this call is that it works with a reduced overall content set, restricted to the items that are available in all devices calling this backwards-compatible API (because old-style devices forbid showing items that cannot be played on the device).

'''Workaround / special error code:'''

• Trying to get recommendations for a only series channel

• Trying to get recommendations for a just created user, not present yet in opengvp data.
