Created Unassigned: Installer always writes to the host despite AddURLsToHOSTS is set to false [20474]

When I set AddURLsToHOSTS = false in the config file the installer still writes to the host.
I have my setting
<WebApplications AddURLsToHOSTS="false">

and it is ignored.

To fix that you need to change the line
in function CreateWebApp

the line
if ($xmlinput.Configuration.WebApplications.AddURLsToHOSTS)
shoud be changed to
if ($xmlinput.Configuration.WebApplications.AddURLsToHOSTS -eq $true)
