Follow redirects to homepage in FP 8

[jamesaoverton]

@safisher points out that ORNASEQ's homepage resolves after a redirect:

OBOFoundry/OBOFoundry.github.io#1009 (comment)

The requests module should automatically follow redirects. Looking into this, this is an issue with the certificate.

Adding verify=False solves this, but could this be dangerous AND we get an InsecureRequestWarning.

We could do certificate verification: https://urllib3.readthedocs.io/en/latest/user-guide.html#ssl
But I suspect we'd get an SSLError here.

Thanks @beckyjackson. What's the specific problem with the certificate?

[beckyjackson]

Here's the exception message:

HTTPSConnectionPool(host='kim.bio.upenn.edu', port=443): Max retries exceeded with url: /software/ornaseq.shtml (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])")))

It passes with verify=False, but then I get the warning:

InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings

Thanks again @beckyjackson. It's weird that I don't see similar problems using other tools, such as cURL and Safari.

@anitacaron during your next Dashboard revision, can you prioritise this?
