Removing source files should not raise an error when using a jump host and the source files set is empty

Current Situation

Removing source files raises an error when using a jump host and the source files set is empty in case of operation="copyfrominternet".

Normally a resultset file is created on the jump host which is used as file list for the later deletion of the source files.
Unfortunally the resultset file is not created in the case of an empty source file set so that the "delete" operation raises an error because it doesn't find the resultset file.

Desired Behavior

Removing source files should not raise an error when using a jump host and the source files set is empty.
