[BUGFIX] Avoid reflection for public property injection

The property injection in the ObjectContainer always
did reflect the object and made the property accessible,
even if the property was public and therefore accessible
by default.

With this patch, reflection is avoided for public
properties which increases the performance of public
property injection a lot.
