Only render badge value if there is no icon and no image

[spacegaier]

Breaking change

Proposed change

The previous condition to check if the value string should be rendered looked at the class members, not at the actually determined values in the render() function.

Also the value string render condition resulted in both icon and value being rendered inside the badge. No the value is only shown if no image or icon is determined.

    badges:
      - entity: climate.test_thermo
      - entity: light.office_ceiling
      - entity: input_number.num_test
      - entity: alarm_control_panel.home_alarm
      - entity: binary_sensor.movement_backyard
      - entity: camera.demo_camera
      - entity: camera.demo_camera
        icon: mdi:police-badge-outline
      - entity: camera.demo_camera
        image: /local/spacegaier.jpg
      - entity: sensor.tablet_a7_akkufullstand
      - entity: sensor.tablet_a7_akkufullstand
        icon: mdi:police-badge-outline
      - entity: person.test_user
      - entity: person.ada

Before: Both badges that have an image are also showing the value plus the third last badge that has an icon defined shows icon and value.

The !icon && !image is technically redundant since I ensured we only determine a value for the same condition further above (to safe some performance) but I felt having this condition again here explicitly makes it more clear.
