inconsistent await for endSession

[ElectricNroff]

https://github.com/CVEProject/cve-services/blob/54aa5ab9ab6ad8bad5f6d66fb867b2dd64c1bff4/src/controller/org.controller/org.controller.js
has several instances of await session.endSession() (e,g., in updateUser) but also several instances of session.endSession() (e.g., in createUser). Also, endSession is often called twice (e.g., before a return within a try when it is subsequently going to be executed within finally).
