remove price set options from UI if only CiviMember is enabled
When only CiviMember is enabled as active component, menu for setting new price sets (civicrm/admin/price) is visible, but throws an DB syntax error.
When CiviContribute is also enabled, the same menu works, since price sets are meant to create/interact with contributions.
Since CiviContribute and CiviMember are two distinct components, I consider this as a bug.
Expected behaviour is that menu for new price sets only appears on UI if CiviContribute is enabled.
