Description

When using init command with --template option, template's placeholderName is not being replaced in package.json's scripts section.

Reproducible Demo

I've tried different placeholderName forms:
e.g template/package.json scripts:

"ios:dev": "react-native run-ios --scheme HelloWorldDevelopment",
"ios:dev": "react-native run-ios --scheme \"HelloWorld-Development\"",
"ios:dev": "react-native run-ios --scheme \"HelloWorldDevelopment\"",

e.g template.config.js:

module.exports = {
  placeholderName: "HelloWorld",
  titlePlaceholder: "Hello App Display Name",
  templateDir: "./template",
};

react native init MyTemplateTest --template my-template

The resulting package.json scripts:

"ios:dev": "react-native run-ios --scheme HelloWorldDevelopment",
"ios:dev": "react-native run-ios --scheme \"HelloWorld-Development\"",
"ios:dev": "react-native run-ios --scheme \"HelloWorldDevelopment\"",

Same as in template, while I expect HelloWorld to be replaced with provided project name e.g. MyTemplateTest

Thanks for submitting a report. It seems that we handle package.json in a special way, which causes us to not replace everything correctly. I already started working on a fix here.
