Clicking Proposal from Proposals view with session timeout does not resume correctly

[jlmuir]

Steps to Reproduce

1. Go to the Proposals view and wait for your session to time out such that whatever you do next will redirect you to the SynchWeb log-in view.
2. Click a Proposal. Since your session has timed out, you will be taken to the log-in view.
3. Enter your log-in credentials and click Login.
4. You are taken to the Visit List view.

Expected Behavior

The Visit List view displays the list of visits.

Actual Behavior

The Visit List view displays a busy indicator and does not display the list of visits.

Presumably because during the login process the proposal has been lost, so the visits list doesn't know which proposal you are requesting. We should at least fail more cleanly and potentially redirect back to the proposals page.
Have made internal ticket LIMS-1174 to work on this.
