Issue #3512046 Update crypt method names stored in cryptsetting.

After upgrading to drd 4.1.7, the cryptsetting field in the drd_domain table contain keys with names that need updating. If not, $passord in Drupal\drd\Crypt\Method<MethodClass> will be empty. That in turn make the 'args'-field in BaseEntityRemote::remoteRequest() empty, which cause communication with the a specific drd_agent to fail.

Closes #3512046
