ENOENT: no such file or directory, chdir

Bug Report

$ react-native-macos run-macos
...
    export SOURCE_ROOT=/Users/xxx/mac/macos
    export SRCROOT=/Users/xxx/mac/macos
...
ENOENT: no such file or directory, chdir '/Users/xxx/mac/macos' -> 'macos'

The app itself works... the build exits with error though.

Folder structure:

• mac (project root)
  • macos
    • build
    • mac
    • mac.xcodeproj
  • node_modules
  • rn-cli.config.js

To Reproduce

Install from scratch as per readme. Then run react-native-macos run-macos.

• macOS v10.14.6
• react-native-macos v0.19.3
