Use Addressable::URI.join to merge base_uri and visit_uri

[akmhmgc]

Description

If Capybara.app_hostcontains / at the end (eg. http://www.google.com/) and visit_uri.path exists, visit_uri_parts[:path] return the path having // and the test fails like below.

Capybara.app_host  = "http://localhost.local/"

it 'failed_test' do
    visit "/path"
    # page.current_path returns  '//path' and test fails
    expect(page).to have_current_path '/path'
end

So, I use Addressable::URI.join.

path1 = '/'
path2 = '/path'

Addressable::URI.join(path1, path2).path
# => "/path"
