Remove capybara-webkit

It no longer installs on macOS Sierra (the [wiki] recommends checking
out an old version of Homebrew to install Qt5.5), making it difficult to
run tests on a new computer.

In addition, we don't have any Javascript tests.

Thus, the easiest thing is just to not use capybara-webkit.
