broken-link-checker: TypeError: Cannot assign to read only property 'response' of object '[object Object]'

Describe the bug During a recursive ordered broken link check, blc starts checking and successfully finding broken links, then part of the way through, it hangs, and eventually dumps out a TypeError:

-
/usr/local/lib/node_modules/broken-link-checker/node_modules/bhttp/lib/bhttp.js:159
  err.response = response;
               ^

To Reproduce npm install -g broken-link-checker blc https://example.com -ro

Expected behavior A completed broken link scan.

Environment:

• OS and version: macOS Catalina 10.15.3
• Node.js version: v13.10.1
• broken-link-checker version: 0.7.8

Possible (terrible) workaround: Manually go to the last page checked prior to the error, and test each link on that page in your browser. Then remove any links from the page that timeout, for example, links that go to domains that no longer exist.
