Capybara monkey patch causes raise_server_errors to be evaluated at the wrong time

[afn]

We generally have Capybara.raise_server_errors set to true, but some of our rspec examples need to disable Capybara.raise_server_errors. To this end, we use an around block:

config.around(:each, ignore_server_errors: true) do |example|
  old_value = Capybara.raise_server_errors
  Capybara.raise_server_errors = false
  example.run
  Capybara.raise_server_errors = old_value
end

With pry-rescue enabled, Capybara checks raise_server_errors too late, after the value has already been reset to old_value.

I've fixed this by updating the monkey patch to account for this scenario. Will post PR shortly.
