Subject: async_map_utils: Pass key_printer also for reporting pending tasks...

...in async map instances, same as for reporting cycles.

This removes the restriction that the key object has to posses the
ToString method, allowing it to be used, e.g., with just-mr maps.

The now obsolete HasToString concept is removed.
