Avoid squashing/humanizing the exception when config[:verbosity] == 2btm/knife-backtrace

We create an instance of Chef::Knife::Bootstrap in knife-ec2, but we've
already processed ARGV so we substitute and process an empty argv.

config[:verbosity] comes from Chef::Application::Knife. Normally we
merge those options with the ones from the knife subcommand in
Chef::Knife.run. Since we don't in this case, we don't set it to the
default of 0 that is specified there, leaving it nil.

We set Chef::Config[:verbosity] to config[:verbosity] in Chef::Knife#initialize
which now becomes nil.

This change makes it so we do not update Chef::Config[:verbosity] if
config[:verbosity] is nil, so that later when we rescue we don't call
humanize_exception if Chef::Config[:verbosity] is 2.
