As of 8446a40, pass show will include a newline when showing a password.
This causes the pass helper here to reliably fail to initialize since a
password doesn't round-trip.
Before making this change, the pass test would fail if the installed
password-store version was v1.7.1+, and after this change it passes
again.
Fixes#107

when a credential isn't present, so let's do that.
