Don't delete a file twice if -i is given on the command line

If sarg is ran with command line option -i, in some circunstances I have
yet to clarify, the ip file is not produced. In that case, the name of
the previously created file (whose name is still in the string buffer)
is deleted a second time. The result is a failure as the file doesn't
exists any more.

Thanks to Arnaud Florent for reporting this bug.
