reload-modified should start with reload-rows

[cool-RR]

When I use reload-modified, I expect to immediately see the updated version of the sheet, and then to have it continually updated as new rows are written. The second part works, but the first part doesn't. I have to wait for a row to be written before I see all the rows that were written between the time I opened the sheet and the time I invoked reload-modified. I think there should be a reload-rows call at the start of reload-modified.

This is especially important when you use reload-modified on a sheet that isn't being written to anymore. You still want to see the latest rows.
