Fix Spring Security configuration in tests

As of spring-projects/spring-security#11653, Spring Security's [at]Enable*Security annotations are not meta annotated with [at]Configuration which breaks some of our tests.

This commit adds missing [at]Configuration annotations where needed.

Closes spring-projectsgh-2118
