optout fe2d6e25e0 Change CChain::Contains() to take reference ...

The `CChain::Contains()` method dereferences its input without checking,
potentially resulting in nullptr-dereference if invoked with `nullptr`.
To avoid this possibility, its input is changed to a reference instead.
Call sites are adapted accoringly, extra nullptr-check is added as
needed.
