fix ef-password to pass tests. (#89)

`ef-password --length 10` is technically valid, so making the excluseive set of --secret_file, --decrypt, and --plaintext be required was a bad assumption.

Updated unit tests for cognito

Forgot to update unit tests for cognito lookup.

Fixed return value of cognito lookup

use to return this

return "arn:aws:cognito-identity:${{AWS::Region}}:${{AWS::AccountId}}:identitypool/{}".format(identity_pool_id)

now returns this
return "arn:aws:cognito-identity:{{{{REGION}}}}:{{{{ACCOUNT}}}}:identitypool/{}".format(identity_pool_id)

relieves the pain of debugging on the user end in cloudformation on why it doesn't work if they don't put it in Fn::Subs in the old version.
