InvalidProjectFileException after upgrading VS2017 to 15.8.0 with Microsoft.Build NuGet 15.6.82

### Steps to reproduce

Using Microsoft.Build package (from NuGet in version 15.6.82) added as NuGet reference to a project.
Calling constructor of: Microsoft.Build.Evaluation.Project(projectFile) in one of methods.
Results in throwing Microsoft.Build.Exceptions.InvalidProjectFileException
Stack Trace:

```[ERROR] Microsoft.Build.Exceptions.InvalidProjectFileException
[ERROR] Invalid static method invocation syntax: "[Microsoft.Build.Utilities.ToolLocationHelper]::GetPathToStandardLibraries($(TargetFrameworkIdentifier), $(TargetFrameworkVersion), $(TargetFrameworkProfile), $(PlatformTarget), $(TargetFrameworkRootPath), $(TargetFrameworkFallbackSearchPaths))". Method 'Microsoft.Build.Utilities.ToolLocationHelper.GetPathToStandardLibraries' not found. Static method invocation should be of the form: $([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(`a`, `b`)).

Unfortunately, because product is already released it's hard to fix existing issue. Users who updated their VS2017 to version 15.8.0+ will suffer from not being able to use product.

Is there any workaround?

### Expected behavior
Using this constructor should be backward compatible even if user has Microsoft.Build in version older than 15.8.X

### Actual behavior
Throws an exception because usage of newly added method which was not present in older version.
