Compiling a project while any editor process is open triggers a hot reload

If you attempt to compile a project while an editor process is running, even if it is of another project entirely, it will hot reload the project instead of doing a normal compile. This can create issues with projects that don't have their .dlls yet as the correct .dll will not be generated. The process that is open must be the same engine version for this to occur.

Regression?: No

1. Create two code projects and compile them both (Both projects need to be in the same editor version)
2. Open the first project in the editor
3. Remove the Binaries folder from the 2nd project
4. Compile the 2nd project in Visual Studio
   Result: The project is hot reloaded instead of being properly compiled
   Expected: The project is properly compiled

Visual Studio immediately compiles to a hot reload dll
