Fix related to issue #13, Trouble with singleTask

Hello, as stated by [ktamilvanan](https://github.com/ktamilvanan) adding a `newIntent()` override resolve the issue with `singleTask` and `singleInstance`.

Please apply the Pull Request or add your own fix, but close this issue. It's very critical be able to receive url-scheme destination with `singleTask` launchMode.

Btw thanks for the great plugin!
