Does not display the error message when importing user that it reports to itself

[SinergiaCRM]

Issue

When saving a user, the CRM validates that a loop is not generated with the reporters ("Reports to" field) so that a user cannot report to himself or any of his managers can report to him.

This validation is implemented for the process of saving/updating a user from the user interface but causes an alert with a label that does not exist in the process of updating users through an import.

Possible Fix

No response

Steps to Reproduce the Issue

1. Create a normal user who reports to himself.
2. Check that when saving an error is displayed because he cannot report to himself
3. Export the user and in the downloaded document change the name of the user and the ID of the user to whom he reports ("Reports to" column), where we will indicate the ID of the user himself
4. Run the Import and Update process and check that, although no error message is displayed, the user is not updated.

(Optional)
5. Create another user who reports to the first
6. Export both users and modify the first user so that it reports to this second user.
7. Run the Import and Update process and check that, although no error message is displayed, the users are not updated

+Optional
8. Extend the chain of reporters and perform the checks.
