dest_file in task convert is wrong

[Flavio Percoco]

The dest_path is not formated correctly, which ends up in converting the image to a path that is completely ignored by other tasks.

    Make sure the converted image is imported

    Turns out the converted image is being completely ignored. This is
    because the `file_path` provided by the ImportToFS task cannot be
    overriden by other tasks. In order to fix this, I've dropped all the
    extra suffixes that we've been using in favor of working on the actual
    `file_path` directly.
