Namespace is created too late

Problem

When deploying synapse I got errors:

[…]
================================================================================
Prepare minio
================================================================================

Error from server (NotFound): error when creating "minio-policy.yaml": namespaces "eole3-synapse" not found
Error from server (NotFound): error when creating "minio-job.yaml": namespaces "eole3-synapse" not found

The namespace is created too late by the helm deployment.
