Title:
Race condition related to integration/install infobar

Bug description:
When browsing to a website for which a WebApp exists, an infobar
appears to inform the user of the situation and propose an
installation of the associated WebApp.
The issue appears when multiple tabs are involved and one selects
another tab while the current one is loading webpage for which a
WebApp is available (but not installed or authorized). The infobar
appears in the environment of the proper tab, but the text is empty.
[Test Case]
- have more than one tab opened (with blank pages),
- in one of the tabs, go to a website that is supported by webapps (e.g.
Twitter),
- immediately after (BEFORE the website loads), switch to the other tab
(Ctrl+Tab),
- wait a bit for the original website to complete loading,
- when one comes back on the loaded tab, an infobar should have popup but
with NO text on it,
[Regression Risks]
The code deals with the infobar that the user sees when a WebApp is about to
be installed or needs authorization. A malfunction might prevent WebApps from
being installed or no installation message could be displayed.
Technical:
--------------
There is a race condition in the infobar javascript that incorrectly
uses a chrome.extension.getSelected function to get its current tab is
a ask the background page for its text (since the infobar cannot
receive init() data and has to get it from somewhere). The tab request
is asynchronous hence the timing sensitivity of the operation.
