Rename getProfiles to getProfileIds and add a proper getProfiles method

[scottinet]

Description

• User.getProfiles is renamed to User.getProfileIds
• User.getProfileIds now returns an empty array instead of null if no profile is attached to the user object
• add a new User.getProfiles method fetching profiles from Kuzzle API and returning an array of Profile objects
