Settings.ps1 wrong IdentityServerUrl after merge

[byrondelgado]

Hi,

I noticed that the merge of the commit dcfc40a - [#449] [9.1] Updated install and uninstall for 9.1 - overrided the IdentityServerUrl in file settings.ps1.

Currently, the file shows the settings as

# Identity Server Parameters
$IdentityServerSiteName = "${SolutionPrefix}_IdentityServer.$SitePostFix"
$IdentityServerUrl = "https://$IdentityServerName"

where IdentityServerName should be IdentityServerSiteName instead. Variable $IdentityServerName doesn't exist.

Thanks
