Error on template creation/edition

Not sure how to reproduce. I created a template with a series of properties and saved. Then edited the template and added more properties and modified others. When attempting to save I got:

As a user, I have no idea what the error is about, we need better feedback.

I checked the error logs, and this appears to be a managed error, so no trace on the notifications. Further search lead me to:

 "errorResponse": {
  "message": "E11000 duplicate key error collection: xxxx.translationsV2 index: language_1_key_1_context.id_1 dup key: { language: \"en\", key: \"Question\", context.id: \"691b9d330b548b7bd933af67\" }",
  "code": 11000,
  "writeErrors": [
   {
    "code": 11000,
    "index": 0,
    "errmsg": "E11000 duplicate key error collection: xxxx.translationsV2 index: language_1_key_1_context.id_1 dup key: { language: \"en\", key: \"Question\", context.id: \"691b9d330b548b7bd933af67\" }",
    "op": {

The culprit seems to be, I modified the label for the title property to be the same as the label for the template title. Ideally, these are two translation keys totally different.

Also, ideally users get better error information.

For the moment, we should fix the error reporting and put a validation on the frontend.
