Initialize ChromeClient timeout with default Capybara timeout

[francisbeaudoin]

When using session.visit(), if the page includes indefinitely running Javascript, apparition hangs and never timeouts.

To reproduce the issue, create an HTML page having the following code and session.visit it:

<script>
    while(true) { }
</script>

Observe apparition hanging indefinitely.

To fix the problem, I'm initializing the ChromeClient with the session_wait_time value.
