SKIP_CACHE_LOAD flag doesn't work when authentication is enabled

The flag is ignored, this doesn't happen in upstream.

Steps to reproduce:

• set up a cache with an eviction size 2, and a file store
• put in 3 entries
• get entries with cache.withFlags(Flag.SKIP_CACHE_LOAD).get

Result:

• all entries are retrieved

Expected result:

• only entries that are in cache - not evicted should be retrieved
