This module is not sorted, we cannot just do assertions based on line
index.
Instead we do two different approaches:
 - When there is only one "empty" draft transaction, we check locate the
line based on the state cell and then check each cell relatively to that
first xpath
 - After we had a second draft, we just check that we have two lines
matching each cell predicate.

Sometimes test fail we don't have any information about what the problem
was.

Using the same technique of turning a promise into "a function called
several times until it returns true or false", we can get rejection
failures in the selenium error message.

The term (used for example on HTTPExchange_view/my_follow_up_title ) is
"Follow-up". This will fix testNamingConventions failure.
