wcst_import imports original input file path instead of replaced one when using pre-hook

[Bang Pham Huu]

When using pre-hook and it changes the input file path by replaced one, wcst_import should use this updated file instead.

e.g: Input file path is a jp2 at a folder and replaced file path is a tif at a different folder, then, wcst_import should use the tif file to import.
