DeployRunner: Fix regression caused by role selection

This reverts commit 31c9cdf.

The role selection does not work, because:
- The label is actually called `roles`
- The `roles` label is an array, so `=` comparison with a role string does not work
- Deployer selector does not support a comparison operator to check if an array contains a value
