fix: trying to stop app on simulator may kill CLI

[rosen-vladimirov]

In case you use tns run ios --path <path to app> --device <simulator GUID>, CLI will try to stop the application, but may kill CLI instead. The problem is in ios-sim-portable, which incorrectly searches for application PID. Update the package to 4.0.7 where the issue is fixed.

What is the current behavior?

On iOS Simulator:

• CLI is unable to stop application which has grep in the name, so LiveSync is not working in this case.
• CLI process is killed when tns run ios --path <path to app> --device <device GUID command is used.

What is the new behavior?

CLI successfully syncs the application.

Fixes issue #4284
