Insert virtual history items for sites like www.google.ca in auto-suggestion url

• Submitted a ticket for my issue if one did not already exist.
• Used Github auto-closing keywords in the commit message.
• Added/updated tests for this change (for new code or code which already has tests).
• Ran git rebase -i to squash commits (if needed).

When a site is visted for a deep linked page or with parameters
the history item is stored with the complete parameters and links.
Often after a user visits the site a number of times, the expectation
shifts such that the simple domain should be the first suggestion
in the url bar suggestion list. The canonical example is when a
user searches Google a number of times via the url bar. After three
searches www.google.com will be added as a virtual history item in the
search results.

Auditors: @bbondy, @BradRichter

Test Plan:

1. Clear history
2. End three searchs from the url bar without accessing www.google.com
3. Open a new tab and type goog - ensure a history item for www.google.com is displayed
