The only tests that have COMPLETE* support for the debugging sink
are the advanced_testcase and the database_driver ones (store and
report). So we must ensure that the rest of tests don't use the
debugging sink at all.
Right now we are using it for storing, but later there is not
reporting, so any debugging happening within non advanced tests
is not detected.
This commit just ensures that we stop making that storing for
non advanced/database_driver tests. Nothing more, nothing less.
* Note that we have had to add a few missing bits to the
database_driver testcase because it was not 100% complete. Now
it behaves 100% the same than the advanced_testcase one regarding
the debugging sink.
All the setup/teardown/pre/post/conditions template methods
now are required to return void. This was warned with phpunit 7
and now is enforced.
At the same time, fix a few wrong function names,
provider data and param types, return statements...
