[FIX] {crm_livechat,utm}: set no update

Steps to reproduce:
1) Install utm module.
2) In link tracker edit utm named LinkedIn or any and add another with same name.
3) update the module.

We get an error that utm_medium or utm_source should be unique.

create goes through `_get_unique_names` method so its only a problem
when updating the record.
