getProjectInfo and loadProject don't seem to work now and aren't tested

[dsyme]

FSharp.Formatting picked up a dependency on getProjectInfo (which uses loadProject), but they no longer seem to work.

I note these don't have tests in this repo so we should add those

The error I was getting was:

  skipping project 'FSharp.Formatting.Markdown.fsproj' ... error - The SDK 'Microsoft.NET.Sdk' specified could not be found.  

I think because they don't know toolsPath. Anyway I replaced getProjectInfo by this snippet I found in the test suites

        let loadProject (path: string) =
                let cwd = System.IO.Path.GetDirectoryName path |> System.IO.DirectoryInfo
                let toolsPath = Ionide.ProjInfo.Init.init cwd None
                let tfm = ProjectLoader.getTfm path (dict extraMsbuildProperties)
                let readingProps =
                    Ionide.ProjInfo.ProjectLoader.getGlobalProps path tfm extraMsbuildProperties
                    |> Seq.toList
                    |> List.map (fun (KeyValue(k,v)) -> (k,v))
                let loader = WorkspaceLoader.Create(toolsPath, readingProps)
                loader.LoadProjects([ path ], customProperties, BinaryLogGeneration.Off) 

That seemed to improve things though I now get another error:

  skipping project 'FSharp.Formatting.Markdown.fsproj' because an error occurred while cracking it: System.Exception: error - System.ArgumentException: The input sequence was empty. (Parameter 'source')

Closing this, as both mentioned functions are under test now for many different SDK bands in the test suite.

Thank you!!!!
