Fixup StrutsConverterFactory

It should delegate back to ObjectFactory#buildBean instead of directly
calling Container#inject, otherwise overrides of buildBean in subclasses
of ObjectFactory e.g. SpringObjectFactory are skipped; meaning that
TypeConverters cannot make use of Spring dependency injection

Fixes: https://issues.apache.org/jira/projects/WW/issues/WW-5524
