Update command failed.

Describe the bug
I tried to update an account manually (intentionally restrictive IAM permissions prevent the rotate command from working) and received an error

To Reproduce
Steps to reproduce the behaviour:

1. Ran Command 'awskeyring update ACCOUNT_NAME'
2. entered my new key and secret..
3. got the error

$ awskeyring update personal-aws 
       access key id: AKIAXXXXXXXXXXXXXXXX
   secret access key: ****************************************

Expected behaviour
Yup, didn't expect this to happen, should just work.
