Window title not retained when switching tabs

Thanks for filing an issue! Please answer the questions below so I can help you.

• iTerm2 version:3.0.20161002-nightly
• OS version:10.11.6
• Attach ~/Library/Preferences/com.googlecode.iterm2.plist here (drag-drop from finder into this window)com.googlecode.iterm2.plist

Detailed steps to reproduce the problem:

1. In Preferences -> Appearance -> Window & Tab Titles, uncheck all
2. In Profiles -> Default Profile -> Terminal, check "Terminal may set tab/window title"
3. In a tab, execute `echo -en "\e]2;window title\a"
4. Select a different tab

What happened: Window title changed from "window title" to "Shell" (or other tab's title) when the new tab was selected

What should have happened: Window title should have stayed to the set title, given that all window title settings were disabled in preferences

May be related to Issue #4999

Each tab has a notion of its own window title. I agree this doesn't make sense. Titles in general need a serious revamp.
