Issue description

When editing a control split into a partial class, the designer generates a new resource file for each file contributing to the partial class. This makes compilation impossible, as the generated resource files conflict with each other.

Steps to reproduce

1. Clone the repo https://github.com/CyrilPaulus/WinFormDesignerPartialResourceBug
2. Open the file Form1_partial.cs with the WinForm Designer.
3. The file Form1_partial.resx should have been generated.
4. Try to compile the project.
