Repetitive steps separated by data-table get ignored

[saw-jan]

In the following feature example, the second When step must be marked with warning.

Scenario: some description
  When something is done using data table
    | name | value |
    | haha | hehe  |
  When again something is done

But the there is no warning in the second When step.
Concerned Rule: repetitive_step

• add unit test
