A transferred file should not be deleted in case that a rename is set and the regular expression doesn't match the transferred file

Problem: We have a profile with replacing/replacement to rename the target files where the regular expression of the replacing parameter doesn't match the transferred files.

;all files starting with an 'x' will be transferred
file_spec = ^x.*$
;all transferred files starting with an 'y' will be renamed
target_replacing = (y)(.*)
target_replacement = \1;\2.transferred

JADE deletes an already existing file (overwrite_files=true) before the rename. If the new filename is equal to the original filename then the original file is deleted.

Approach:
JADE checks before the rename JADE wether the original and the new filename are equal. If yes the a rename is unnecessary and JADE aborts the rename
