NullReferenceException in NavigationService

[richjhart]

Android API: Android 8.1
Mapbox Navigation SDK version: Navigation Library 0.13.0

Steps to trigger behavior

At this stage, unsure what triggered it, but I've seen it more than once. It might be if startNavigation() is never called (in which case the service will never set the mapboxNavigation object)

Expected behavior

Actual behavior

Hey @richjhart 👋 thanks for reaching out and report your issue.

Could you add some more information for reproducing the NullPointerException (minimal example) or any other specifics around your test setup? Do you have some more information on used device? If there is any sample or pseudo code you can provide that would be really helpful.
