Keep each model's parent out of its JSON (closes #177)
Every reference from a model to the record it belongs to is now
json:"-", so the webhook and target models (and the other parent and
child pairs in internal/database) can no longer marshal each other in
a loop. Preloading maps associations without reading json tags, so it
still fills these references. One test preloads a webhook with its
targets and entrypoints and a target with its webhook, checks the
references are filled, and checks the JSON leaves them out; another
builds each other model with its parent set and checks the parent's
id is absent from its JSON.
