Bug 25723: (QA follow-up) Handle holiday and exception on same day

When a holiday is entered, then exceptions generated on a range, there exists both a holiday and exception in
the special holidays table. We should cache the exception over the holiday instead of both

Also, !1 in perl returns '' rather than 0, so we should explicitly set the value

Add blank line to clear pod error from qa tools
