Fix EZP-21613: Compound\LogicalAnd serialization fails

When doing sub-requests with ESI or Hinclude, Symfony generates a link via the Fragment framework, serializing information that need to be retrieved when catching the subrequest. SiteAccess is serialized as well, which also includes the matcher used.

In the case of Compound matchers, some properties were problematic (and unneeded), so they have been removed from serialization operation via `__sleep()`.

Regression test has been added.
