Fix null exception after creating a space in an new org

[richard-cox]

• fixes Org Summary: Not all content shown #3326
• We previously nuked the org's spaces param when creating or deleting an org
• Validation was correctly then going to refetch this param, however waitForEntity is broken (see Entity service waitForEntity returns too early #2327) and emits an invalid org entity without a spaces param
• Later code takes invalid entity and tries to access spaces param
• Fix, aside from Entity service waitForEntity returns too early #2327, is to update org spaces param after space creation instead of nuking and waiting for validation to refetch it

Other fixes

• Found sub leak in edit org stepper
• endpoint service allApps is subbed to in many places, ensure we share
