[REG 3.2.2 -> 3.3.0] Custom Executable cannot be run

1. Create a new project.
2. Go to Projects mode, Run settings.
3. Add a Custom Executable run configuration.
   The automatically set working directory is "%{buildDir}".
4. Try to run this.
   This will fail. In "Application Output" you can read "Failed to start program. Path or permissions wrong?"
5. Check "Run in terminal".
6. Try to run this.
   This will fail. In "Application Output" you can read "Cannot change to working directory "%{buildDir}": The system cannot find the file specified."
7. Remove the value from the "Working directory" edit.
8. Try to run this.
   Now it works.

"%{buildDir}" should be expanded correctly. In Creator 3.2, this worked.
