Renaming new material before saving doesn't always work

[WYVERN2742]

From quick user study:

1. Create a new material via dropdown on new sample
2. Change material name and properties (do not click save)
3. New material will not be selected on the sample

Looks like material changes are not synched before sample settings are changed;

Fixed in cd3f4660ccc2d2ba0ed228969d5005b90629c31e, awaiting merge.

Main issue was remote changing material ID, and frontend referencing old materialID in selection. Solved by awaiting a response from backend for new material creation.
