Resynchronize organization entries when initializing the server

**Is your feature request related to a problem? Please describe.**
If `GITPLOY_ORGANIZATION_ENTRIES` is changed, the existing permissions are not synchronized. It can be problematic because a user usually doesn't set `GITPLOY_ORGANIZATION_ENTRIES` precisely in the first place.

**Describe the solution you'd like**
Resynchronize permissions when the server initializes.
