Julian Oes 176d932f23 mavsdk_tests: prevent missing updates
It seems like we are often missing updates from topics like flight mode
or in air state, both topics that are sent out infrequenctly e.g. at 1
Hz. Therefore, instead of polling for that data we should probably
subscribe to the updates and that way get notified of each an every
update.

For instance this should prevent the case where we miss the mode change
from mission to descend and back to mission once landed and disarmed.
