prevent usage of keyring in test_process_auth_dont_resolve_alias

[endorama]

During testing for #86 there was a failing test (test_process_auth_dont_resolve_alias) only on my local machine.

The test was failing (remotely) because the Google Password: prompt was presented when not expected.

Test were failing only on Travis, and not on my laptop, which was unexpected. Also, test where failing using the origin/master branch ( in my fork ) up to date with upstream/master, which was unexpected because Travis build for upstream master are green. This shown that the problem is not related to the PR #86.

So:

• test failing on local machine for origin/master up to date with upstream/master
• test not failing on Travis
• test not failing on local machine the first time
• test failing on local machine after the first time

This was happening because that test was writing in the my laptop keyring :sweat: : at first run the pass value was saved in the keyring, making all successive test run failing. The Google Password prompt, which was expected, was not run after the first time, because the value was being retrieved from keyring.

This PR force the config mock keyring to False, in order to never use the keyring: this way the prompt is always present and tests are happy.
