[DataLens On-premises] Source avatar title conflicts with another avatar

ERR.DS_API.AVATAR.TITLE.CONFLICT

The error occurs when adding multiple tables with the same name to the dataset.

To fix this error:

• If the error points to a source table, try removing it from the dataset and adding again.
• If the error points to a subquery as a source, modify the subquery header so that the source names in the dataset do not match.
