[omnibox] [rich-autocompletion] Fix trailing space matching history URL

The History URL provider cleans up trailing whitespace from the input
when matching suggestions. However, using this clean input for rich
autocompletion results in inputs like 'g   ' matching suggestions like
'google.com' which would be displayed as 'g   |[oogle.com]'. This CL
uses the original input for rich autocompletion in the history URL
provider.
