Family demographic verification process URL error

[ChurchCRMBugReport]

The link that the verification process creates is missing a slash and so creates an invalid URL. So, instead of "ourdomain.com/external/verify" it has "ourdomain.comexternal/verify" and that obviously does not work.

Line 98 in api/routes/people/people-family.php changing from
return $response->withJSON(["url" => SystemURLs::getURL() . "external/verify/" . $token->getToken()]);
to
return $response->withJSON(["url" => SystemURLs::getURL() . "/external/verify/" . $token->getToken()]);
fixes it.

Well it fixes it for when you choose the URL from the dialog, but the URL in the email remains broken in the same way.

AND when I chose the email verification, I DO get the email (with the strange "\\\\\\\\" text) and the bad URL, but I ALSO get the following dialog error each time:

`Erreur de communication de l'API avec: /api/family/253/verify

Erreur du texte: parsererror SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data`
