Fix bugs with customFields identified in Issue #3574

Fixed bug with the reference to the customFieldValue in the cards.js

Activity Insert was not being passed the listId, swimlaneId which was required when building the webhook text string.

Added customField and customFieldValue as default values for the webhook msgs. There is no good reason to exclude these (they will only be included when changing a customField anyway). Updated the docker-compose comment to reflect this change.
