`NSGroup.update()` errors, WAPI returns "Field is not allowed for update: is_multimaster"

[pieterlexis-tomtom]

I'm using version 0.6.0 of the connector to update an NSGroup (adding a grid secondary). However, when I call .update() on the NSGroup object, the WAPI (version 2.13.5, from NIOS 9.0.5) responds with HTTP 400 with this error:

{
   "Error": "AdmConProtoError: Field is not allowed for update: is_multimaster",
   "code": "Client.Ibap.Proto",
   "text": "Field is not allowed for update: is_multimaster"
}

I managed to fix this issue in the client by applying this patch:
