Field displayed as Required even after the requirement is updated

https://github.com/aslakknutsen/plugin-arquillian/blob/forge2/src/main/java/org/jboss/forge/arquillian/command/ContainerConfigurationCommand.java#L107

The ContainerValue option is displayed as Required during first init, but when a containerOption that has a defaultValue is selected, the containerOption is no longer required. This change is not reflected in the UI as the * is still shown.
