Commit message

Postpone keyring.errors import.

Description of the change

We import the keyring module late because it does environment-dependent backend initialisation at import time, and we want to postpone this until we actually need it; importing it early can also cause test problems. We need to take the same care when importing keyring.errors.

I think this will fix failures on Ubuntu's autopkgtest runners (e.g. https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-focal/focal/amd64/p/python-launchpadlib/20200415_171509_0c21d@/log.gz).
