matchcode.io update

[JonoYang]

The matchcode api has some issues:

• [] matchcode.io runs out of memory on sha1 matching stage #533

The poll_match_results step on scancode.io side has a problem when polling match projects:

'str' object is not callable

Traceback:
  File "/opt/scancodeio/aboutcode/pipeline/__init__.py", line 199, in execute
    step(self)
  File "/opt/scancodeio/scanpipe/pipelines/match_to_matchcode.py", line 77, in poll_matching_results
    matchcode.poll_until_success(self.run_url)

             ^^^^^^^^^^^^^^^
