[API] PUT a new visit for a candidate fails

[spell00]

Describe the bug
New visits can't be added using PUT requests to the endpoint /candidates/{candidate}/{visit} using the correct request. It works with an incorrect request (see Additional context below for details).

To Reproduce
Steps to reproduce the behavior:

1- Login using a POST request to the \login:

curl https://<your-hostname>/api/v0.0.3/login -d '{"username": "<your-username>", "password": "<your-password>"}'

2- Store the token in a variable.

~$ token='<a-really-long-string>'

3- The following command should work, but doesn't:

curl -X PUT -H "Authorization: Bearer $token" https://test-loris-dev.loris.ca/api/v0.0.3/candidates/115788/V1 -d '{"CandID":"115788","Visit":"V1","Site":"Rome","Battery":"Stale","Project":"Rye"}' returns an error.

What did you expect to happen?
The PUT request should return nothing. Go to https://<your-hostname>/api/v0.0.3/candidates/115788/, the visit V1 should be present, but is not.

Additional context
curl -X PUT -H "Authorization: Bearer $token" https://test-loris-dev.loris.ca/api/v0.0.3/candidates/115788/V3 -d '{"CandID":"115788","Visit":"V1","Site":"Rome","Battery":"Stale","Project":"Rye"}' should fail, because the visit in the url should be V1. However, the PUT request works this way and V1 is added successfully
