Half a minute is more than enough for the test to finish even in the slowest
browsers and in case of starving the PHP FPM process pool, one has to wait
for only half a minute to try again.
The "document ready when jQuery loaded asynchronously" test fails all the time
in iOS7 and sometimes in other browsers. Bumping the timeouts *might* help
these other browsers to be less flakey here.
