Process GRD products outside the tile coverage

When processing 2 tiles, the second one is processed with GRD products downloaded for the first tile, even if there is no intersection.

The results is empty product generated for the tiles, because no intersection

Example:

Tiles 34MDD and 34MBD

Time period:

• first_date : 2018-01-01
• last_date : 2018-02-01

polarisation : VH

The 3 last images in 34MBD are empty because there is no intersection of these products and the tile. However these images are generated.
