bpo-33584: Fix several minor bugs in asyncio. (GH-7003) (GH-7005)
Fix the following bugs in the C implementation:
* get_future_loop() silenced all exceptions raised when look up the get_loop
attribute, not just an AttributeError.
* enter_task() silenced all exceptions raised when look up the current task,
not just a KeyError.
* repr() was called for a borrowed link in enter_task() and task_step_impl().
* str() was used instead of repr() in formatting one error message (in
Python implementation too).
* There where few reference leaks in error cases.
(cherry picked from commit 6655354afcd116c27486bb5ba1dfa50b369d8d85)
