Bug: baseContents callback does not fail gracefully with undefined args

[johniblake]

Scenario:

generatePackageJson({
      outputFolder: 'dist',
      baseContents: (
        {
          name,
          version,
          dependencies,
          peerDependencies,
          publishConfig,
          peerDependenciesMeta,
        },
      ) => ({
        name,
        version,
        main: 'index.js',
        module: 'index.esm.js',
        dependencies,
        peerDependencies,
        publishConfig,
        peerDependenciesMeta,
      }),
    }),
 

When peerDependencies, publishConfig, and peerDependenciesMeta don't exist in package.json but are destructured in the generatePackageJson function definition, the error output is Error: Unable to save generated package.json file, check "outputFolder" option. Consider updating the error handling around this! Thanks.
