2.0.3 with one role won't write credentials file

[snoopytrb]

Describe the bug
Using 2.0.3 if you only have one role available the java window will log into the console instead of writing the token back to the .aws/credentials file

To Reproduce
Steps to reproduce the behavior:

1. Run okta-aws tool as normal, sign in with MFA
2. If you only have one role the java window will continue through to the console instead of closing and writing the credentials file.

Expected behavior
If only one role is available tool should automatically write that role to the credentials file.

I have seen this in our organization as well and have started looking into it. Stay tuned for fix. Hopefully soon 🤞
