donet publish doesn't modify web.config when --output is above the project directory

[mattdwen]

Steps to reproduce

• Create a new web app project in VS at c:\projects\webapp1
• From the CLI, in c:\projects, run `dotnet publish .\webapp1\project.json --output .\pubtest

If you run dotnet publish --output ..\pubtest\ from inside the webapp1 directory it works fine.

Expected behavior

The published web.config to be correctly updated with the relevant parameters.

Actual behavior

web.config isn't updated, and the the CLI spits out:

Configuring the following project for use with IIS: './pubtest'
No web.config found. Creating './pubtest\web.config'
Could not find a part of the path 'C:\Projects\WebApplication1\pubtest\web.config'.
System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Projects\WebApplication1\pubtest\web.config'

   at Microsoft.AspNetCore.Server.IISIntegration.Tools.Program.Main(String[] args)
publish: Published to ./pubtest

web.config looks like:

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <!--
    Configure your application settings in appsettings.json. Learn more at http://go.microsoft.com/fwlink/?LinkId=786380
  -->

  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/>
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false"/>
  </system.webServer>
</configuration>

If you then publish this to Azure you get a CGI error.

Dupe of https://github.com/dotnet/cli/issues/3528?

Yeah, I'd say it's the same.

Closed as dupe.
