Text overrides report errors for nested components

When someone defines:

• a component containing
  • an instance
    • containing a text
• and this text gets modified in the instance of the component

Then the Importer will report an error. This is due to the fact that the text overrides implemented in the past do not support nested component overrides.

With Qt Bridge export complete instances enabled the error will be reported but the text will be correct (overridden). Without this option the text will not be correct (overridden).
