This is horrible user experience on mobile, user can accidentally touch the
image and then get redirected to captcha.net website which is generally not
useful. As far as a I understand their conditions of use, they don't require
use to make a link to their website.

It seems this never worked, it was comparing a string received from the client
with a number from the session.

 * expose firefox console and error logs in `geckodriver.log`
 * expose `geckodriver.log` in the folder testnodes expose on http
 * fix some cases where test were detected as "did not run" and cases where "did not run" tests were not reported as failures

We are already closing Storage on shutdown (see nearby Storage.close call in
the patch), but the DB handle was not closed. With classic ZODB it does not
really matter in practice, because not closing DB is only leaking RAM resources
and the program is anyway terminated soon.

However with wendelin.core 2 things are different: in addition to ZODB storage
server, there is also synthetic WCFS filesystem from which files are opened
and memory-mmaped. In runUnitTest we start both ZODB and WCFS servers and we
also shut down them both in the end. The filesystem server can be cleanly
unmounted and shutdown only when there are no opened files left on it.

Wendelin.core 2 client works by complementing each ZODB connection (zconn) with
WCFS-level connection (wconn) to WCFS server. Those two zconn and wconn are
kept in sync by wendelin.core 2 client logic: whenever zconn adjusts its view
of the database, so does wconn. And whenever zconn is garbage collected, so
does wconn is closed to release resources and close corresponding files opened
on WCFS. In addition to garbage-collection, wconn is also closed when zconn.db
- the ZODB DB handle via which zconn was created - is closed. This is needed to
be able to reliably trigger freeing WCFS resources, because even after DB is
closed, zconn can still stay alive forever being referenced from some python
object - e.g. a frame or traceback or something else.

The latter scenario actually happens during runUnitTest run. As the result it
leads to inability to unmount and stop WCFS server cleanly:

    $ ./runUnitTest --load --save --with_wendelin_core -v erp5_core_test:testWendelinCore
    ...
    test (erp5.component.test.erp5_version.testWendelinCore.TestWendelinCoreBasic) ... ok

I've debugged things a bit and even with
kirr/ZODB@bbd03b3a ZODB connection stays alive
being referenced from some frame objects.

-> Fix this problem by explicitly closing ZODB DB nearby tests shutdown before call to wcfs_server.stop

This is not really for errors during the test itself, but for errors when
ERP5TypeFunctionalTestCase manipulates browser to execute selenium test.
