Update coverage to 5.0.1

[pyup-bot]

This PR updates coverage from 5.0 to 5.0.1.

Changelog

5.0.1

----------------------------

- If a 4.x data file is the cause of a "file is not a database" error, then use
a more specific error message, "Looks like a coverage 4.x data file, are you
mixing versions of coverage?"  Helps diagnose the problems described in
`issue 886`_.

- Measurement contexts and relative file names didn't work together, as
reported in `issue 899`_ and `issue 900`_.  This is now fixed, thanks to
David Szotten.

- When using ``coverage run --concurrency=multiprocessing``, all data files
should be named with parallel-ready suffixes.  5.0 mistakenly named the main
process' file with no suffix when using ``--append``.  This is now fixed,
closing `issue 880`_.

- Fixed a problem on Windows when the current directory is changed to a
different drive (`issue 895`_).  Thanks, Olivier Grisel.

- Updated Python 3.9 support to 3.9a2.
