Update test-connection.yaml

[pwretmo]

"{{ .Release.Name }}-memgraph-test" does not generate a unique name, which is required when a helm chart includes multiple instances of the memgraph chart.

For example when a chart has two dependencies on memgraph:

dependencies:
- name: memgraph
  version: ~0.1.0
  repository: https://memgraph.github.io/helm-charts
- name: memgraph
  alias: memgraph2
  version: ~0.1.0
  repository: https://memgraph.github.io/helm-charts

Hi @pwretmo, thank you for the contribution. The plan is to wrap up #22 tomorrow, with Memgraph 2.17. @antejavor, the maintainer, will be back from vacation next week and then he'll review this PR and include it in the next release. I hope that works for you 🙏
