SNOW-1540431 Init ocsp local cache even if cache server is disabled

[sfc-gh-pfus]

Description

SNOW-1540431 Before this change local cache was not initialized when cache server was disabled, even though we still used it. Cannot reproduce in automatic tests, as driver is initialized once for all tests.

Checklist

• Created tests which fail without the change (if possible)
