fix(python): fix deprecated collections.abc usage (#5195)

Many classes within collections were moved to collections.abc in Python
3.3 -- their usage as imported directly from collections is now
deprecated as of Python 3.7 and will be removed soon.

The fallback import added in this PR can be removed entirely when
support for versions of Python prior to 3.3 is dropped.
