Rename ios project name with new template (facebook#24292)

Summary:
With new `init` implementation we replace all occurrences of the project name (`HelloWorld`) inside `ios` and `android` directories. For some reason, a product name field in `ios` was named wrongly. This shouldn't impact initialization using `global-cli`

[iOS] [Fixed] - Change productName in iOS in new init.
