AbstractNavitiaProvider: Fix NullPointerException.

Browse source 
4f7bd832e6 introduced a
NullPointerException in AbstractNavitiaProvider.
The call to Context() in line 970 calls prevQueryUrl.toString() and
nextQueryUrl.toString().
The variables are however null in the case that the search returned
only one result. The easiest way to reproduce this is searching
for two very near locations. The result will then be one walk-route.
This commit fixes the NPE by restoring the old behavior and has been
tested in Transportr.
