Wrong source bindings when using `existingCommunicationsSecretName`

[Pawel Kosiec]

Description

Source bindings are not properly set when using existingCommunicationsSecretName.

Expected behavior

When using existingCommunicationsSecretName, runtime-config doesn't have source bindings from the secret, but from default configuration instead.

Actual behavior

Steps to reproduce

Ok, I could reproduce that with existingCommunicationsSecretName :

k create secret generic --from-file /tmp/comm_config.yaml -n botkube comm-config.yaml

Where /tmp/comm_config.yaml is:

communications:
  'default-group':
    socketSlack:
      enabled: true
      channels:
        'default':
          name: 'k8s_devops_azure'
          bindings:
            sources:
              - k8s-custom
      botToken: 'xoxb-...'
      appToken: 'xapp-...'

And then I ran

helm install botkube --version=1.4.1 -f /tmp/user-values.yaml -n botkube botkube/botkube
