_ArrayUnique fails on single element array when base set to 1

[Melba23]

When using the $iBase feature to ignore the first element, the function hard fails on a single element array.

Global $aArray[1] = ["test"]    ; add a single row to the array
_ArrayUnique($aArray, 0, 1)     ; Arguments: $iColumn = 0, $iBase = 1 (1-based)
