Publisher has hard time finding subscribers #33

When using ros2 topic int /some_topic and ros2 topic echo /some_topic ros2_client doesn't necessarily find any subscribers with get_subscription_count or wait_for_subscription. I used the orignal node.

This was s bug in the new implementation of Send Futures returned by wait_for_subscription and wait_for_publisher. They tended to get stuck due to improper handling of Futures. This is now fixed in release 0.7.5.
