[candidate_profile] Error handling when loading widgets

[AlexandraLivadas]

Brief summary of changes

This PR changes the candidate_profile template that loads the widgets of the candidate_profile page so that it catches the errors when loading candidate visit information. Specifically, this handles the issue where a candidate is affiliated with multiple sites and the user only has access to one of those sites and the candidate_profile page does not load.

Testing instructions

1. Create a user with access_all_profiles permission and only give them permission for one site
2. Find a candidate that has some of its visits at the site your user is affiliated with and some of its visits at other sites your user should not have permission for
3. Go to the candidate_profile page of this candidate
4. See that the page loads correctly
5. See that the list of visits does not include any of the visits that your user doesn't have permission to view.
