Fixed issues discovered in integration (#1469)

- some scenarios require libraries.json to be a different path from the
  SDK installation directory, update DartUri and ExpressionCompilerService
  to allow for that.
- Fix a bug where `dartEmitDebugEvents` was set as a `String` instead of
  `bool` in the injected client.
