[~TASK] FLOW3 (Cache): Fixed a failing APC backend test

One test was failing, probably due to an old APC version used (see #9538).
After upgrading to a more recent version of APC (3.1.5-dev) this other
tests failed due to the cache slam prevention mechanism.

Since that cannot be disabled (currently) via ini_set(), these tests
are now skipped if apc.slam_defense is set to 1.

Relates to: #4855
Resolves: #9538

With 3.1.5-dev the mentioned error is gone.

However, with the default php.ini settings I now get:
