Ignore certificate errors in Chrome

[sidonath]

After upgrading Chrome to version 79, our app's test suite started producing a steady stream of warnings like the following one:

140361933186816:error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown:s3_pkt.c:1487:SSL alert number 46

Additionally, all actual HTTPS requests fail, which, in turn, fails our tests expecting those requests to be successful.

I'm not sure what exact change in Chrome triggered the warning that wasn't showing before, but the only two ways to remove it are:

• Add the ignore-certificate-errors flag to Chrome
• Stop using Puffing Billy

Since not using Puffing Billy is not really an option, we can only ask Chrome to ignore all certificate errors. This clears the warnings and makes the tests expecting HTTPS requests to succeed to pass.

Also added a spec that fails on the current master branch without ignoring client certificates:

$ bundle exec rspec spec/lib/billy/browsers/capybara_spec.rb                                                                                                                                            -- INSERT --
