wallet: make CanGetAddresses() const

CWallet::CanGetAddresses() is used to check whether the wallet has available or is able to produce keys for addresses. It uses the ScriptPubKeyMan::CanGetAddresses(), which in turn uses the const KeypoolCountExternalKeys() method, all which do counting and no modifications.
