Add clean up logic to navigator.credentials layout tests

Add clean up logic to navigator.credentials layout tests

navigator.credentials is backed by MockCredentialManagerClient when
running layout tests. If two tests are run in sequence on the same
content_shell, the earlier test's configuration affects the following
one. Actually, passwordcredential-fetch.html is consistently failing.

Fix this by adding clean up logic to user of the mock configuration
API.

Fix this by adding clean up logic to user of the mock configuration
