Edited Issue: package restore doesn't work for projects added after enabling it [2822]

1. create webapplication1<br />2. install jquery package.<br />3. enable package restore (which would add the nuget.targets import to the project<br />4. add new web application2<br />Actual:<br />Package restore is not enable for web application 2 and there is no UI option to enable it. <br />workaround is to manually add the import. and <RestorePackages>true</RestorePackages><br /><br />expected:<br />- since I have already enabled package restore for the entire solution it should have automatically added import for nuget.targets
