Unconnected wells caused a node without strays to be put in the Thyme file. Such nodes are now skipped and a warning is issued.

The same thing happens also if there are instances with unconnected ports. An empty node is now inserted in the Thyme output and the warning message is much less visible (people complained they were anoyed by it).
