[key_store] export if version = 1

[florianlenz]

Feature / Issue

Hi. In the tali release we changed the whole library to use AES CTR. Old key stores are encrypted using AES CBF. Old key stores have the version 1. New key store version 2. In the case you have an old key stores (which can be checked based on the version) you need to export it again with the user password and you will have the new one. Thats basically it.

Acceptance criteria

• Export key stores again to get the new key stores
