[BUGFIX] QueryGenerator getTreeList negative ids

When persistence.recursive is configured when using a command controller no
records can be retrieved because the storagePid is negated in the
AbstractConfigurationManager, while claiming all implementations of getTreeList
support negative ids. Using abs() on the id when it is negative fixes this.
Also see the ContentObjectRenderer implementation of getTreeList
