[BUG] first_entry is different when accessing node through Cloud about netdata-cloud

[chrikar]

To provide some background on this, the netdata children are configured to stream their data to the parent, which is configured with a dbengine and a big retention period. So if we go to the parent's netdata page we can see all this information that the children have sent by accessing the parent's db. However, from the cloud we are now still contacting the children directly to request the data, and the children were configured to have really small history of 60 in their stream.conf.

We have now increased this to 3600, so we should have at least 1 hour of data in the children, until we are able to get the data we want from the cloud directly from the children.
