[REF] mass_mailing: rename mail.mail.statistics and reporting model

PURPOSE

Mass mailing is currently a bit messy. As SMS will be added as a way to notify
people in mass through SMS let us take this opportunity to somehow clean this
application: organization, light code cleaning, model renaming.

SPECIFICATIONS

Rename mail.mail.statistics to mailing.trace and mail.statistics.report
to mail.trace.report. Rationale :

  * mail.mail.statistics is linked to mail.mail model. Soon this model will
    hold data related to SMS sending. It makes sense to be broader in the
    naming;
  * mailing.trace is more inlined with marketing.trace model that is the
    marketing automation model using it in marketing automation (enterprise
    application);
  * mailing.trace is shorter to write;
  * mail.statistics.report model should sense to be updated at the same
    time;

MIGRATION

mail.mail.statistics model -> mailing.trace
mail_mail_statistics table -> mailing_trace
mail.statistics.report model -> mail.trace.report

fields updated (w column change)
  * link.tracker.click: mail_stat_id -> mailing_trace_id

fields updated (no column change)
  * mail.mail: statistics_ids -> mailing_trace_ids
  * mail.mass_mailing: statistics_ids -> mailing_trace_ids
