…_managers` entry

In the method `CWallet::LoadActiveScriptPubKeyMan`, the map
`external_spk_managers` (or `internal_spk_managers`, if parameter
`internal` is false) is accessed via std::map::operator[], which means
that a default-ctored entry is created with a null-pointer as value, if
the key doesn't exist.  As soon as this value is dereferenced, a
segmentation fault occurs, e.g. in `CWallet::KeypoolCountExternalKeys`.

The bevaviour can be reproduced by the following steps (starting with empty regtest datadir):

$ ./src/bitcoind -regtest -daemon
$ ./src/bitcoin-cli -regtest -named createwallet_name=wallet descriptors=true blank=true
$ cat regtest-descriptors.txt
