Issue Summary

For users who are using SSO with CBA, when attempting to sign into the desktop application, it doesn't populate a choice for selecting a certificate and thus fails to let the user log in.

Steps to Reproduce

Non-reproducible unless you happen to have SSO with CBA.
If this is you, can verify by:

1. Open the Desktop Trello App
2. Attempt to sign in via your SSO
3. Once you get past the first barrier, you will be met with the error.

Expected Results

User logs in.

Actual Results

User is getting a certificate failed error and cannot proceed.

Workaround

• Use the browser/web version of Trello, as that will allow a certificate to be selected and can log in correctly.
