Using the config_tmdpir fixture across all tests in this module caused
a lingering LineParser to make test_debug fail.
I still don't know why, but scoping the config_tmpdir fixture to only
the test class that was creating ~/.config/qute_test fixes the issue,
and still prevents creation of a user tempdir.
This was more complicated than the other data/config/cachedir test
fixes, as QtWebEngine was accessing the datadir directly (and bypassing
standdarddir.data).
This means the tmpdir_data stub is not enough, we need to set
XDG_DATA_HOME to redirect access.
Don't create ~/.config/qute_test by mocking out standdarddir.config for
all tests in this module.
This adds config_tmpdir to fixtures.py and moves temp_datadir from
test_adblock to fixtures.py as it will be needed more broadly.
Running test_standarddir would pollute the user's home with
`~/.cache/qute_test`.
The `no_cachedir_tag` fixture was supposed to prevent this, but was not
working because [usefixtures does not work on fixtures]
(https://github.com/pytest-dev/pytest/issues/1014).
This fixes the fixture to actually prevent cachedir creation, but
applies it to tests individually (or by class) rather than with autouse
because the cachedir tests cannot pass if it is working.
Running the tests would create ~/.config/qute_test and
~/.local/share/qute_test on the user's machine. The test_standardir
module needed a bit more mocking to prevent it from cluttering the
user's machine.
Two tests that created the data dir were fixed by passing basedir in
args, and one test that created the config dir was fixed by patching
os.makedirs to a noop.
Per one of the diff comments on #1597:

> At some point I should probably change it to a list everywhere 😉
- The invalid URL will now get encoded when using QUrl.
- The check for a None url_text is somewhat pointless as I don't think
this can ever happen in the real circumstances.
