Item12471: "Print on closed file handle" crash in configure checker when LocalSite.cfg cannot be written.

See Support.Question1276

    open my $fh, '>', $name
      || return 'Could not create test file ' . $name . ':' . $!;

needs to become

    open my $fh, '>', $name
      or return 'Could not create test file ' . $name . ':' . $!;

This needs to be checked elsewhere, but 2 occurrences are in Checker.pm.

Cursory check of the rest of Foswiki didn't find any other examples like this.

But a semi-related error was found, the BasicSanity checker results are never returned to the user even when the system status is considered "insane".
