NoSuchBeanException exception is thrown when validator is disabled

[mancze]

Expected Behavior

It should be possible to disable Micronaut validation via configuration micronaut.validator.enabled = false.

This is useful, for example, in tests that want to send/read invalid data and make assertions about it.
Note: For simplicity, the linked example application disables the validator in the actual application, not just in the tests.

Actual Behaviour

Exception is thrown:

Unexpected error occurred: Failed to inject value for parameter [validator] of class: io.micronaut.validation.validator.DefaultValidatorFactory

Message: No bean of type [io.micronaut.validation.validator.Validator] exists. The following matching beans are disabled by bean requirements: 
* Bean of type [io.micronaut.validation.validator.DefaultValidator] is disabled because: 
   - Property [micronaut.validator.enabled] with value [false] does not equal required value: true

Steps To Reproduce

1. Run ValidatorTest in the example application.
