[VS] Solution Explorer displays some folders out of order

[majocha]

For example FSharp.Editor project:

AutomaticCompletion is first:

Should be before Hints:

VS 17.10.0 Preview 2.0
I don't recall seeing this in previous versions.

I started seeing this as well.

I don't think we own that part. Unless we change ordering "in runtime" in targets, this should be investigated by project system. @KevinRansom I remember you've changed something regarding content includes in the past month or so.

This is actually caused by the EnableDefaultNoneItems change.

It turns out that the project system discovers Folders as a consequence of <SomeItem Include="path to files" />
EnableDefaultNoneItems causes folders and .fsi files to be located in the solution folder, prior to the <Compile Include="" />

This causes folders and .fsi files to be displayed in the wrong order.
