Describe the bug
If I delete a wild card certificate from the list of ssl certs so that I can recreate it with new dns credentials (because there doesn't appear to be an edit function so that you can update. credentials or change dns hosts) and then create it again you then get errors in the logs like this:

nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/npm-5/fullchain.pem": BIO_new_file() failed (SSL: error:80000002:system library::No such file or directory:calling fopen(/etc/letsencrypt/live/npm-5/fullchain.pem, r) error:10000080:BIO routines::no such file)
nginx: configuration file /etc/nginx/nginx.conf test failed

It appears to be trying to use the same directory for the cert that was there before because it appears to think it still exists somehow.

Nginx Proxy Manager Version
v2.12.3

To Reproduce
Steps to reproduce the behavior:

1. Go to SSL Certificates
2. Delete an existing wildcard cert.
3. Create the same wildcard cert again, but change the dns challenge credentials
4. See error

Expected behavior
Should create a new entry or recreate the folders etc. properly.
