[FIX] web,mail: keep changes when scheduling an activity

The problem occurred in form view, in edit mode, when the user
did some changes in the form, and then clicked on 'Log or schedule
an activity'. When validating the activity, the fields mail_activity
and mail_thread were reloaded but all changes were discarded in the
process.

This rev. ensures to reload the requested field without discarding
the changes.
