Resource designer files generated are incompatible with netstandard

Resource designer files generated are incompatible with netstandard if a desktop framework is included first in the ``TargetFrameworks`` list.

### Steps
1. Create a new netstandard library with VS 2017
1. Add a resource file to the project
1. Change ``$(TargetFramework)=netstandard1.3`` to ``$(TargetFrameworks)=net45;netstandard1.3``
1. Right click on the resource file and select ``Run Custom Tool``
1. Rebuild

### Expected
The project will build

### Actual
The project fails to build with an error about being unable to find the ``Assembly`` property.

### Observation

When a desktop framework is first in the list of target frameworks the designer file is generated incorrectly for netstandard.

``.GetTypeInfo()`` is missing from the designer file:

```global::System.Resources.ResourceManager temp = new global::System.Resources.ResourceManager("ClassLibrary12.Resource1", typeof(Resource1).Assembly);```

Using netstandard only you would get:

```global::System.Resources.ResourceManager temp = new global::System.Resources.ResourceManager("ClassLibrary12.Resource1", typeof(Resource1).GetTypeInfo().Assembly);```

### Workaround
Using ``$(TargetFrameworks)=netstandard1.3;net45`` instead of ``$(TargetFrameworks)=net45;netstandard1.3`` generates the correct file.
