fix: only-new-issues should return empty string for fetchPatch

fetchPatch determines the patchPath. If the patchPath is not empty, the action explicitly overrides user input and sets --new-from-patch=<patch_path>, --new=false and --new-from-rev to be empty. only-new-issues should obviously set --new to be true.
