Creating a plugin in a C++ project opens a second instance of Visual Studio

Note
If creating the project outside of Binary, build the project in VS, but do not close it.

When creating a new plugin, the editor compiles the project and opens in Visual Studio. If the project is already opened in Visual Studio, it will cause error messages (please see attached image)

I would expect the editor handles this like it handles creating a new C++ Class and focus on the Visual studio that is already open, or opens a new one if the project is not already opened in Visual Studio

This is a Regression from 4.15.3

1. Create a new C++ Project
2. Leave Visual Studio open
3. Under Edit, select Plugins
4. Select New Plugin
5. Select Blank and name it BlankTest
6. Select Create Plugin

Result The editor compiles the new plugin and opens a new instance of Visual studio and causes an error message

Expected Result: The editor checks if the project is opened in Visual Studio and only opens if it is not opened
