AthenaConfiguration: Clean up some bogus warnings from CA->legacy conversion.

The value of a ServiceHandle property is read back as a string, so don't warn about that.

A ToolHandleArray normally can differ between instances being merged; demote the message for that from warning to debug.

This merge request affects 1 package:

• Control/AthenaConfiguration

This merge request affects 1 file:

• Control/AthenaConfiguration/python/LegacySupport.py
