Fix not starting emulator during debug command

`tns debug <platform>` command should start emulator in case device is not attached. The current command does not start emulator as we have passed `skipInferPlatform` - when this option is used, devicesService does not know for which platform to start the emulator.
Fix this by passing correct options.
