The parseIamArn method was making assumptions about the input arn being
properly formatted and of a certain type. If users tried to pass a
bound_iam_principal_arn that was malformed (or was the ARN of the root
user), it would cause a panic. parseIamArn now explicitly checks the
assumptions it's making and tests are added to ensure it properly errors
out (rather than panic'ing) on malformed input.
