CR-5515 OPENIG-150 'Host' Http header does not reflect changes in target URI
Indeed, the host http header wasn't replaced when doing a rebaseUri,
but not only in this case, with the setUri too.
To solve this problem, a simple fix would be to do an update of the headers
when getting them.

- A unit test has been added for the DispatchHandler case.
