Calling aws.TemporaryCredentials constructor with a single param is broken in 2.382.0

[anton-107]

This code used to work prior to version 2.382.0

const credentials = new aws.TemporaryCredentials({RoleArn: roleArn});
// and then temporary credentials are passed to a constructor or a AWS service

In 2.382.0 the first line throws an error:

TypeError: Cannot read property 'masterCredentials' of null
at TemporaryCredentials.loadMasterCredentials (/var/task/node_modules/aws-sdk/lib/credentials/temporary_credentials.js:113:35)
at new TemporaryCredentials (/var/task/node_modules/aws-sdk/lib/credentials/temporary_credentials.js:62:10)
...

This was caused by #2451 and is resolved by #2456.

@jstewmon is correct. For now, you can rollback to 2.381.0. The fix in #2456 will be included with the next release of the SDK.
