Minor improvement: --exclude-caches is in cmd twice

[berti34]

Hi George,

just a notice: the --exclude-caches is always twice in the backup cmd:

command: C:\WINDOWS\SYSTEM32\restic.exe backup --json --exclude-caches C:\Portable C:\Privat -o sftp.args=-oBatchMode=yes --exclude-caches --tag plan:S3-DTSMS-Win-01 --tag created-by:DTS-LAP-028 --exclude *~ --parent ... --exclude-file C:/Portable/BackRest/excludes-file.txt
