Fix coverage upload

Usage of `coverage` stores data in the internal `.coverage` file that is not supported^1
by codecov.
This results in silently (because we dont use fail option by default) not uploading coverage.

This fixes it by runnin `coverage xml` in coverage_report which outputs a compatible file in `coverage.xml`
