installation: deprecate tests_require and fix tox configuration

Amends installation setup with respect to deprecated `tests_require` and
`pytest-runner`.

Amends `tox` testing setup to fix mocker fixture import issue.

Improves `tox` testing setup to produce correct coverage findings by
forcing "editable" package installation mode. (In its "editable-legacy"
variant which is necessary for Python-3.6 that we are still supporting
in the client.)
