When creating a new channel from a blueprint that reuses an existing hst configuration, it cannot be displayed in the channel mngr

Problem is that if a new channel is added from a blueprint, and that new channel only contains unique content but points to the same hst:configuration as an already existing one (by 'hst:configurationpath'), then that new channel won't be visible in the channel mngr. Only way to expose this new channel is by adding a new hst configuration that extends from the existing hst:configuration (and can even inherit the channel node but better to copy it)
