Changing taxonomy term id looses existing content values
With the new ability to change terms identifiers (see #72 & #113), we can now change the identifier of a term, even if it is already used on a content (value selected on the behavior). As there is no migration code in the pull request, the existing values are then "lost".
IMHO, we should :
- migrate the existing values used (if their identifier changed)
- prevent user to change terms identifiers that are already used
- or at least warn the user in the control panel
@Petchesi-Iulian @ale-rt @alecghica @avoinea what do you think of this ?
