Improved handling of already terminated instances
Improved handling of already terminated instances

It is possible to create an instance, terminate the instance and then
attempt to recreate the instance with the same parameters. In this case
`ec2.run_instances` returns a reservation list containing the instance ids
but the logic gets stuck waiting for the instance to exist in the call to
`ec2.get_all_instances`, even if wait is no).
