Home content may still appear after logout

[jeremydouglass]

While investigating #173 I realized that a separate issue was confusing my testing. This is a single-installation issue, and I tested it on a clean single installation.

Sometimes after logging out of BicBucStriim the content from the homepage may continue to appear.

1. Open browser tab to /bbs/
2. Log in (e.g. as admin)
3. Close browser tab
4. Reopen a new browser tab to /bbs/ (you are still logged in)
5. Click "Log out"
6. Click "Home"

Problem: At this point the homepage book list loads, making it appear you are still logged in. Continuing to navigate however reveals that you are not (browser-based login challenge appears or bounced to Login).

Weirdly, when I skip steps 4-5, I don't encounter the issue. Also, if I perform steps 4-5 after clicking "Log out" I don't encounter the issue.

Tested using BicBucStream on Synology DS713+ (DSM 5.01) with Chrome browser version 44.0.2403.107 (64-bit) on OS X.
