Fix E2E test service_ping_default_enabled_spec.rb

What does this MR do and why?

Fix E2E test service_ping_default_enabled_spec.rb

The enable-usage-data-checkbox can have four different states:

• checked and enabled
• checked and disabled
• unchecked and enabled
• unchecked and disabled

Apparently, previously the checkbox was checked but enabled. But currently, by an unknown reason, the checkbox is checked but disabled. We modify the test to check for this state.

This is the 18.1 packport of !195823 (merged)
