Spring Support: Fix tests in IDEA 2017.1

Filter out duplicate reference targets.
Fix test data as directory references are available

Fix test data as Spring @Autowired inspection
no more reports parameterless methods.
Fix gutter checking as configuration bean references now resolve
to @ComponentScan annotation
