"Paste Snippet" does not get contents of qrc file

1. Create a new Qt Quick Application project.
2. In Projects view, right-click the project's qrc file and select "Open in Editor" from the context menu.
   You'll see a graphical editor.
3. Select "Tools" -> "Code Pasting" -> "Paste Snippet..." from the menu.
   The "Paste Snippet" dialog shows up. Its editor is empty or shows the contents of your machine's clipboard.
4. Close the qrc editor.
5. In Projects view, right-click the project's qrc file and select "Open in Text Editor" from the context menu.
   You'll see a text editor.
6. Select "Tools" -> "Code Pasting" -> "Paste Snippet..." from the menu.
   The "Paste Snippet" dialog shows up with the qrc file's content.

The "Paste Snippet" dialog should be able to retrieve the contents of a file even when it is open in a graphical editor. This works for qml and ui files.
