iOS Auto Provision with App Store Connect API v2.1.1

Fixed an issue with setting certificates when the common name contained non-ASCII characters, like: Apple Distribution: xyz (ä) (xyz).

The Xcode Archive Stap failed with:

error: No certificate for team 'xyz' matching 'Apple Distribution: xyz (î) (xyz)' found: Select a different signing certificate for CODE_SIGN_IDENTITY, a team that matches your selected certificate, or switch to automatic provisioning. (in target 'App' from project 'App')
