don't loop indefinitely in confirm method 

Only check for input twice in the meta.confirm method. This prevents an
errant newline from aborting the run while allowing Terraform to exit if
there is no input available. We don't just check for a tty, since we
still rely on being able to pipe input in for testing.

Remove the redundant confirmation loops in the migration code, and only
use the confirm method.
