App restart required when authenticating with assumed roles

[kjones]

When the temporary credentials expire the queries just get errors and the app doesn't re-prompt for a new MFA code. I have to close the app and reopen it to get prompted again.

AWS profile looks something like this:

[main_profile]
aws_access_key_id=MYACCESSKEY
aws_secret_access_key=MYSECRET

[dev]
source_profile=main_profile
role_arn=arn:aws:iam::123456789012:role/Developer
mfa_serial=arn:aws:iam::112233445566:mfa/myusername
region=us-east-1

#227 possibly related - I did discover the "Reload Profiles" workaround after creating this issue so at least I'm not having to restart the app.

Would also like to see the ability to configure assume role duration up to 12 hours.
