Herman Schaaf 4242bd9c83 Replace percent escapes in file URL before using as path
Summary:
This is to fix a bug that prevents bundling of projects that contain spaces (or other special characters) in their names.

#### Reproduction steps before the fix
 1. Create a project with a space in the name:

 2. Follow the steps in `OPTION 2` for running from a bundled file, i.e. create the `main.bundle` file, add it to the project if is not there already, and uncomment `jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];`
 3. Run the application. This is what happens:

To prove that it has to do with a space in the name, refactor the project name to not contain a space:
