Match web_sessions cache pattern only when synchronized

When high-availability has been instructed not to handle web_sessions
(by setting websession.synchronize=false), it should not trigger
web_sessions cache evictions.

In Gerrit, evicting an entry from the 'web_sessions' is equivalent to
logging out the user associated with that session.

Forwarding web_sessions eviction is the correct behavior when their
handling and storing is responsibility of the high-availability plugin.

It is a bug when this happens unconditionally (even when
websession.synchronize=false), because it triggers a log out of that
user from the peer node.

Remove 'web_sessions' cache from the list of default caches that are
always forwarded and, instead, conditionally add it only when
websession synchronization is enabled.
