rgb_timeSeries.js: return empty feature collection

[s7frstel]

It is a amazing and simple to use tool. I encountered a bug because the timeseries chart isn't loading. I tried to find the bug, although I am not that familiar with javascript. I think the bug is in the rgb_timeSeries.js in

[161] .filter(ee.Filter.notNull(col.first().bandNames()));

I am getting an empty feature collections after filtering. I changed the filter statement to .filter(ee.Filter.notNull(['label'])); and then it works. So maybe there is an issue with the bandnames?

I am really appreciating the hard work and effort you put in this. :)
