Import of a trousseau works even without gpg passphrase being submitted

[oleiade]

$ trousseau import trousseau.tr
trousseau imported

$ trousseau show
2014/02/03 15:48:31 Whether no valid private key forstore decryption was available or supplied passphrase was invalid

$ export TROUSSEAU_PASSPHRASE='mypassphrase'

$ trousseau show
abc:123
easy as:do re mi

Shouldn't work

After a quick look I realized the actual $ trousseau import command was more of a "replace data store with pointed file content" rather than a real import.

Closing this issue relies on #53 and #54
