Added two tests for activation key copy

First test verifies that you cannot use a name already taken.
Second test verifies that subscriptions are being copied over.
```
@Test: Copy activation key with duplicate name ... ok
@Test: Copy Activation and verify contents ... ok
```
Bonus: Added the beginings of an activation key search.
It'll just give a numeric code with no text associated. I feel this message is adequate for its purpose, though.
