Rescue OpenSSL::SSL::SSLError in JiraService

What does this MR do?

Catches OpenSSL::SSL::SSLError in JiraService.

Are there points in the code the reviewer needs to double check?

So... we probably need specs here, but as we're not doing anything with these exceptions (except logging), there's really no specs to add. This is technically poor error handling.

Why was this MR needed?

We blow up if we run into a OpenSSL::SSL::SSLError exception when testing the JiraService.
