The requests history not displayed, when link to the session is used

[Sawiq]

To reproduce:

1. Create smocker session
2. make a few requests
3. create another smocker session
4. copy link to the #1 session and open it in a new browser tab.

Expected result: Requests' history displayed in a new tab

Current result: Requests' history seems to be empty. Making a new requests everrides the first session.
