Revert "Fixes a quote issue in rsync command"

This reverts commit c07ff8e870cad140ada90daae100051dc0b30c83.

Reverting because it made "--rsh" not working anymore (the port part were now
ignored).
Fixes pushing the current working directory to destination

The invisible spaces that made rsync push the current working directory to
destination were not because of quotes surrounding the final command but because
$rshPart was, sometimes, an empty string.

Tip: to correctly print the command (or an array in general), use:

    printf "%q " "${rsyncCommand[@]}"

This shows invisibles spaces and empty strings (which echo would not).
