Revert "Merge branch 'NXCALS-1245-fix-tests-for-security-annotated-controllers' into 'develop'"

#Merge request template @acc-logging-team - please have a look for approval.

Reason: @MockBean annotation which is used in SecurityTest class caused AppliationContext to be created multiple times (as many as tests using object with this annotation +1). As in ApplicationDev method startMiniKdc is annotated with @PostConstruct, multiple instances of local KDC were created during running tests, this resulted in errors as only single instance can exist at once.
