Use re.findall() instead of re.search() in message_listener_matches

[albeec13]

Using re.findall() provides better match results in cases where the programmer would like to match the same group multiple times in a single chat message, which would previously only return a single result. Behavior for existing use cases, such as matching two different groups, continues to return a tuple that matches the old behavior or re.search().groups() for backward compatibility. This fixes issue #386

Hi @albeec13, thanks a lot for submitting this PR as well! Before reviewing the changes, can I ask you to add new test patterns in the following test files? You can use the scripts under the scripts directory to easily run tests.

• https://github.com/slackapi/bolt-python/blob/v1.6.1/tests/scenario_tests/test_message.py
• https://github.com/slackapi/bolt-python/blob/v1.6.1/tests/scenario_tests_async/test_message.py

If creating new test files having test_message_ prefix is easier for you, that's also fine!

I've pushed new test cases and validated that they fail before and succeed after the changes in this PR. Should be good to go.

Perfect! Looks great to me 👍
