We finally saw a test where there were *no* errors logged by the
time Cockpit reached the log screen, so there were no entries to
click. Let's just make the test set log level to info before
looking for entries - I prefer this to 'click entry if found,
otherwise change log level' as that's twice as many branches to
look after. Of course, it means the warning triangle entry needle
is useless now :(
