Bug 32671: Prevent selenium/basic_workflow.t to fail if run on slow servers

When submitting the form to create a new patron we are doing a POST
memberentry.pl that is redirecting to moremember.pl

The selenium test is expecting for the end of the request to test the
page's title against "Patron details for ".

But it's only waiting for the POST response (302), not the GET
moremember that will display the patron's details.

You can simulate a slow server using cpulimit: `cpulimit -b -p $PID -l 1`
replacing $PID with the pid of the starman process.

Note that other tests are failing using 1%, but... baby steps.

The current failre:
 #   Failed test at t/db_dependent/selenium/basic_workflow.t line 122
 Wide character in print at /usr/share/perl/5.32/Test2/Formatter/TAP.pm line 125
 #                   'Add patron (test cat description) › Patrons › Koha'
 #     doesn't match '(?^u:Patron details for test_patron_surname)'

The next one (NOT fixed by this patch):

 #   Failed test at t/db_dependent/selenium/basic_workflow.t line 256.
 #                   '
