For the same turnitin_uid account, several records in turnitintooltwo_users with several Moodle's environments

[jmerinogranizo]

Problem description
A user [email protected] with user.id=10 in Moodle environment 1, creates turnitintooltwo task and when accepting the turnitin conditions, a turnitin_uid account (for example 12345) is created and registered in the table turnitintooltwo_users with userid=10 and turnitin_uid=12345.

In another Moodle environment (2) there is a user [email protected] with user.id=10 who has not even accepted the Turnitin conditions so there is no record in turnitintooltwo_users.

The user [email protected] backs up the task in environment 1 and restores it in Moodle environment 2.

Somehow, I don't know yet, a record is created in turnitintooltwo_users with userid=10 and turnitin_uid=12345.

When the user [email protected] (user.id=200 in Moodle 2) makes a submission in Moodle 2, a record is created in turnitintooltwo_users with userid=200 and turnitin_uid=12345. There are two turnitintooltwo_users records with turnitin_uid=12345. And the submission may show that the submitting user is [email protected] instead of [email protected].

Actual Behavior

I have not been able to reproduce the problem but I know these cases are occurring.
