undefined method `[]' for nil:NilClass after upgraging Passenger to 6.0.8

[mrusa]

This is the same problem already addressed in #36. The new Passenger version 6.0.8, released yesterday, has a new output when calling passenger -v, so the regex in https://github.com/capistrano/passenger/blob/master/lib/capistrano/tasks/passenger.cap#L20 does not work anymore.

For me, a temporary fix was to add set :passenger_restart_with_touch, false to my deploy.rb so the regex won't get called.

Now the passenger version looks like this: "Phusion Passenger(R) 6.0.8". So the regex is not working for the "(R)".
