Bump coverage from 6.3.3 to 6.4 in /backend

[dependabot]

Bumps coverage from 6.3.3 to 6.4.

Changelog

Sourced from coverage's changelog.

Version 6.4 — 2022-05-22

• A new setting, :ref:config_run_sigterm, controls whether a SIGTERM signal handler is used. In 6.3, the signal handler was always installed, to capture data at unusual process ends. Unfortunately, this introduced other problems (see issue 1310_). Now the signal handler is only used if you opt-in by setting [run] sigterm = true.

• Small changes to the HTML report:

  • Added links to next and previous file, and more keyboard shortcuts: [ and ] for next file and previous file; u for up to the index; and ? to open/close the help panel. Thanks, J. M. F. Tsang <pull 1364_>_.

  • The timestamp and version are displayed at the top of the report. Thanks, Ammar Askar <pull 1354_>. Closes issue 1351.

• A new debug option debug=sqldata adds more detail to debug=sql, logging all the data being written to the database.

• Previously, running coverage report (or any of the reporting commands) in an empty directory would create a .coverage data file. Now they do not, fixing issue 1328_.

• On Python 3.11, the [toml] extra no longer installs tomli, instead using tomllib from the standard library. Thanks Shantanu <pull 1359_>_.

• In-memory CoverageData objects now properly update(), closing issue 1323_.
