Fix up aws-ts-organizations example

[Frassle]

Two fixes to this example:

Firstly new Organization sets a name not just "" which would cause an error.

Secondly how to get the org id differs between using getOrganization and new Organization` so made a variable for each one to make it easier to switch between.
