Using assume in powershell 7 with -no-cache doesn't fetch new session credentials

[jasday]

Issue Description

When using the assume command in a powershell 7 terminal, it correctly retrieves credentials.

When attempting to use this with the -no-cache command, I am greeted with the message

[✔] [dev](eu-west-2) session credentials will expire in 40 minutes

which is using the existing session, rather than a new one

This is using long-term access keys in ~/.aws/credentials, assuming a role in another account via an iam user that has the access keys.

Expected Behavior

The default session length for this role is 1 hour, so using no-cache should fetching new session tokens for the full hour.

Actual Behavior

Assume is not fetching new session tokens and is re-using old (although still active) ones.

Reproduction Steps

1. Run powershell 7
2. assume a role
3. session token should be retrieved for x length of time
4. assume the same role with -no-cache
5. observe that the session length remains the same
