[dependabot-preview]

Bumps coverage from 5.0.3 to 5.1.

Changelog

Sourced from coverage's changelog.

Version 5.1 --- 2020-04-12

• The JSON report now includes counts of covered and missing branches. Thanks, Salvatore Zagaria.
• On Python 3.8, try-finally-return reported wrong branch coverage with decorated async functions (issue 964). This is now fixed. Thanks, Kjell Braden.
• The ~coverage.Coverage.get_option and ~coverage.Coverage.set_option methods can now manipulate the [paths] configuration setting. Thanks to Bernát Gábor for the fix for issue 967.

Version 5.0.4 --- 2020-03-16

• If using the [run] relative_files setting, the XML report will use relative files in the <source> elements indicating the location of source code. Closes issue 948.
• The textual summary report could report missing lines with negative line numbers on PyPy3 7.1 (issue 943). This is now fixed.
• Windows wheels for Python 3.8 were incorrectly built, but are now fixed. (issue 949)
• Updated Python 3.9 support to 3.9a4.
• HTML reports couldn't be sorted if localStorage wasn't available. This is now fixed: sorting works even though the sorting setting isn't retained. (issue 944 and pull request 945). Thanks, Abdeali Kothari.
