Merge branch '2.3' into 2.7

* 2.3:
  Fixed correct class name in thrown exception
  Add gc_mem_caches() call for PHP7 after itoken_get_all() as new memory manager will not release small buckets to OS automatically
  Removed a duplicated test in CardSchemeValidatorTest
  Fix perf and mem issue when using token_get_all
  [SecurityBundle] fix SecureRandom service constructor args
  Normalize params only when used.
