Since on activation the file is hardlinked from the image to the
location in prefix, you also changed the one in the image. There is no
way to get the original back except rebuilding the port.

Run a 'port destroot <portname>' and then compare the file in
$(port work <portname>)/work/destroot/ with the one in prefix.
