Adjust ini_parse invocation to match method name
Adjust ini_parse invocation to match method name

Tested with a file in $settings::confdir called puppetlabs_aws_configuration.ini with the following content:

[default]
  http_proxy = http://proxy.example.com:80
  region = us-east-1

On a run of 'puppet resource ec2_instance', the variables were read and used.  However, the 'region' parameter in the output code was incorrectly shown as 'eu-west-1'.
