Fix issues with LocalItems keychain after trying to use replacement login.keychain
Fix issues with LocalItems keychain after trying to use replacement login.keychain

Instead use an entirely custom named keychain and set it to be default.
This wasn't working before but that's because ~/Library/Preferences has
to exist for custom keychain settings to be saved properly, and we have
a custom HOME in test which didn't have this dir (silently fails).
