Fix the log path logic so the .\ isn't required

They will try to help a little bit with https://github.com/Microsoft/msbuild/issues/1586, where they might make it so that <Content Include> can accept a folder and create the folder even if empty.

The workaround for now is to either do a <Content Include> with globbing for the logs folder and put a dummy file in the folder, or the dev can just do something along the lines of this ...

<Target Name="CreateLogsFolder" AfterTargets="AfterPublish">
  <MakeDir Directories="$(PublishDir)logs" Condition="!Exists('$(PublishDir)logs')" />
  <MakeDir Directories="$(PublishUrl)logs" Condition="!Exists('$(PublishUrl)logs')" />
</Target>
