RefBase: make Renamer destructor virtual

This patch makes the Renamer class destructor virtual and fixes
the incorrect constructor initialization list ordering.

These issues and related compiler warnings have been suppressed
by the build system which uses the gcc –isystem command
line option, unless a project explicitly adds the include the path
system/core/include to Android.mk and uses the templates.
