FE tool - fix feature editor on the trace layer

[Ben Wyss]

The trace layer has (in part) been constructed with TraceForm.js. It has been based off of the fault_section layer from the FE demo. It currently is not able to write new records properly to GeoServer.

When this error was viewed in geoServer, it was indicated that there was a conflict between the new primary key and an existing pkey in the table. Once I removed all the existing records from the table the issue was solved
