[FIX] web: click on a pivot cell always gives right action domain

Before this commit, with a time range activated in a pivot view,
click on a non empty cell would not always give the right list of
records because of a bad action domain.

The reason is that the headers domain or comparisonDomain were
not always set when appropriate:
    - for the headers 'Total', the corresponding group obtained
      by read_group does not contain the key __domain. For that
      reason both the key domain and comparisonDomain were left
      undefined.
    - for headers that correspond to groups not present in the two
      periods compared, one of the key was left undefined.

With the present commit, we correctly set the domain and
comparisonDomain keys everytime they are useful.
