Major Description
Original issue report: http://stackoverflow.com/questions/23544452/chaining-visitor-validator-in-struts-2.
This bug can be reproduced by nesting two or more visitor validators with a conversion validator in the last validation configuration.
Conversion validator in nested visitor validators doesn't work as expected because getFullFieldName method in VisitorFieldValidator.AppendingValidatorContext returns not a full field name.
This patch makes sure that the correct full field name is returned.
Also the InternalValidatorContextWrapper-s from AnnotationActionValidatorManager and DefaultActionValidatorManager could be removed because they were introduced to fix similar issue with nested visitor validators. See https://issues.apache.org/jira/browse/XW-588 and https://issues.apache.org/jira/browse/XW-618 for more details.
