 (based on [https://help.openstreetmap.org/questions/29395/potlatch-2-wont-
 save-precondition-failed-cannot-create-way-data-is-invalid jc86035's
 report] at help.osm.org.)

 test case:

 1.    Create a way/click on an existing way.
 2.     Press the "Create parallel way (P)" button in the toolbox several
 times.
 3.     Click anywhere on the map.
 4.     There will now be a large amount of ways with no nodes (which you
 will not see).
 5.    Press the Save button, and the error dialog box ("Precondition
 failed: Cannot create way: data is invalid") will pop up.


 I (first created a new two-node way) clicked 5 times on it and had 5 ways
 without any node (visible in the data).
