[Bug]: SYNDisplay outTransform.url not working in OpenRV 3.1

[williamwira]

What happened?

Switching the color pipeline to use a SYNDisplay node used to require an outTransform.url property (I last tested in OpenRV 2.2), and would correctly raise an error when it was not set. However, that property appears to have no effect on the color pipeline in OpenRV 3.1.

In OpenRV 2.2 and older, setting this:
commands.setStringProperty("displayGroup0_colorPipeline.pipeline.nodes", ["SYNDisplay"])
without then setting <syndisplay node>.outTransform.url on the created SYNDisplay node would yield this error:
ERROR: OCIOIPNode: outTransform.url property needs to be set for syndisplay function
Adding a valid icc file path in <syndisplay node>.outTransform.url would remedy the error, and the display color correction would update based on the icc file data.

However now in OpenRV 3.1, no error occurs when the SYNDisplay node is created prior to assigning outTransform.url. Further, assigning an icc file path to the outTransform.url property no longer updates the display color correction.
