Tab spawned from private tab back history not always private.

If I right click the back arrow in a private tab, then middle click one of the pages to open on in a new tab, sometimes it will open in a non private tab.

Tested using Private Tab 0.1.9.1 and Firefox 45 ESR with a new profile.

Just noticed #131, which is somewhat similar to this. I have enabled debugging and caught what it says when this happens:

[Private Tab] 19:13:609 Tab opened: New Tab (empty)
Inherit private state: undefined
[Private Tab] 19:13:617 Selected tab not yet loaded, wait
[Private Tab] 19:13:644 updateWindowTitle() Mozilla Firefox
[Private Tab] 19:13:667 updateTabsInTitlebar() => TabsInTitlebar._update(true)
[Private Tab] 19:13:668 Hide tracking protection icon
[Private Tab] 19:13:668 setWindowBusy(): true
[Private Tab] 19:13:670 setWindowBusy(): false
[Private Tab] 19:13:691 Tab restored, private attribute: false, label: GitHub - Infocatcher/Private_Tab: Adds private tabs, restartless extension for Firefox (20.0+) and SeaMonkey (2.17+)
[Private Tab] 19:13:745 updateDownloadPanel() => reinitialize download indicator

And this is what I get logged when it works properly and opens a private tab:

[Private Tab] 19:41:438 Tab opened: New Tab (empty)

Tab restored, private attribute: false

May be this is something with sessions mechanism... Looks like sometimes tab state isn't updated yet.

But also this may be fixed from "Tab opened: New Tab (empty)" side.
And following fix should help: f08cc14

Test version: private_tab-0.1.9.2pre5-fx-sm.xpi (source code).

[windwakr]

Yeah, that seems to fix it.
