set routing mode to current application mode

Fix a)

AKA jira 100.

After destination is reached, default application mode applies, I didn't change this.

I'm not sure, if we want to set application mode to default application mode in stopNavigationWithoutConfirm(), so I commented it out:
//settings.APPLICATION_MODE.set(settings.DEFAULT_APPLICATION_MODE.get());
But I'm not sure about that.

I changed it back.
Intention was not to change current mode to default mode.
