Minor updates to docs on how to run tests (#8666)
The test runner isn't present in the `[all]` set of extras, so the
previous instructions did not work without also installing `[test]`.

Note that this does not include the `[lint]` extras, since those do not
install on all supported Python versions (specifically, isort 5.x
requires Python 3.6, while we still support 3.5). Instructions for that
are included in our pull request template, so we should be fine there.

I've also dropped the `--no-use-pep517` arg to `pip install` since it
seems to have been added to address a temporary regression in pip 19.1
which was fixed in pip 19.1.1 the following month.

Lastly, updated the example output of the test suite to set more
realistic expectations around run time.

# As of twisted 16.4, trial tries to import the tests as a package (previously
# it loaded the files explicitly), which means they need to be on the
# pythonpath. Our sdist doesn't include the 'tests' package, so normally it
# doesn't work within the tox virtualenv.
#
# As a workaround, we tell tox to do install with 'pip -e', which just
# creates a symlink to the project directory instead of unpacking the sdist.
#
# (An alternative to this would be to set PYTHONPATH to include the project
# directory. Note two problems with this:
#
# - if you set it via `setenv`, then it is also set during the 'install'
# phase, which inhibits unpacking the sdist, so the virtualenv isn't
# useful for anything else without setting PYTHONPATH similarly.
#
# - `synapse` is also loaded from PYTHONPATH so even if you only set
# PYTHONPATH for the test phase, we're still running the tests against
# the working copy rather than the contents of the sdist. So frankly
# you might as well use -e in the first place.
