jsLoad not respect unique index

[EriveltonMS]

Which version are you using? 2.37

Describe the bug when I load a series of data into BD via loadJS, the single index is not respected, and rows are duplicated in the database.

Expected behavior The lines where the single key matches should not be inserted in the database.
