Wrong service selector in ServiceMonitor

[Vovcharaa]

Describe the bug
Under certain conditions vault chart does not install correct ServiceMonitor selector.
When I set values to server.service.active: false and service.ha.enabled: true, ServiceMonitor is created with selector vault-active: 'true' but only service with vault-internal: true label exists.

To Reproduce
Steps to reproduce the behavior:

1. Install chart with provided values
2. Wrong ServiceMonitor is created and target is not observable in prometheus

Expected behavior
ServiceMonitor is created with correct selector
