Issue 656: Bug when adding vector users

[Hzaakk]

Description

When a user is added to (or joins) a project on the Vector cluster, our policy is to automatically grant them access to a specific project on the Savio cluster (namely, the one specified in the SAVIO_PROJECT_FOR_VECTOR_USERS setting). This PR fixes that issue.

Fixes #656

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Added a test case and ran it, ensuring it passed. Also manually tested by joining vector projects.
