[FIX] web_editor: properly save a t-field in a t-ignore environment

When a t-field element was in an editable t-ignore environement,
modifying it was leaving the edit mode style attached to it. This
was because of:
1) When the t-field element was changed, it was marked dirty but
   also its parent editable container. Fixing this, only solves
   the case where only the t-field (and not one of its neighbors)
   is changed but it was worth fixing anyway.
2) Before saving an element, the potential 'o_editable' and
   summernote classes were not removed of its descendant and were
   thus saved.

Bug found with task-38069, merged in stable as it might occur there
too.
