Bug 29485: Trying to prevent administration_tasks.t to fail randomly

Since bug 19185, and Koha_Master running the tests after t/db_dependent/selenium/01-installation.t is ran, t/db_dependent/selenium/administration_tasks.t is failing randomly with:

12:32:59 koha_1       | STRACE:	/usr/share/perl5/Try/Tiny.pm:123 in Selenium::Remote::Driver::catch {...}
12:32:59 koha_1       | 	/usr/local/share/perl/5.28.1/Selenium/Remote/Driver.pm:361 in Try::Tiny::try
12:32:59 koha_1       | 	(eval 1710):1 in Selenium::Remote::Driver::__ANON__
12:32:59 koha_1       | 	(eval 1712):2 in Selenium::Remote::Driver::__ANON__
12:32:59 koha_1       | 	/usr/local/share/perl/5.28.1/Selenium/Remote/Driver.pm:1340 in Selenium::Remote::Driver::_execute_command
12:32:59 koha_1       | 	/usr/local/share/perl/5.28.1/Selenium/Remote/Driver.pm:1340 in (eval)
12:32:59 koha_1       | 	/kohadevbox/koha/t/lib/Selenium.pm:170 in Selenium::Remote::Driver::find_element
12:32:59 koha_1       | 	t/db_dependent/selenium/administration_tasks.t:188 in t::lib::Selenium::click

I don't recreate it locally.

The screenshot of the failure shows that the screen is still on the authorised value list view.

This does not make a lot of sense, but I am failing to find a logic
here.
