2020.1.0a1, sg/keywords (soon to be in master) of 8/12/19

Basically when you change the number of keyword options in a SG using a enum keyword and save, the material still contains the # of keywords before. Even if you create a new material after the save.

Repro:
1) Create a blank SG
2) Create an Enum keyword
3) Change the number of the entries in the keyword to 4 - 8
4) Save the SG
5) Right click on the SG > Create Material
> It will have the right # of options in the drop down menu
6) Go back to the SG, and delete or add some enteries, then save again
> Still has the dropdown options from before

Reproduces even if you create a new material!

Bonus:
It should also be noted that when you first add a new Boolean keyword to a shader that's already in use in the scene, and you set the default to set (after making sure the reference ends with _ON), it will frequently not have the keyword set right. Fixing this requires set & setting the keyword in the material. This will reproduce again if you change the keyword's reference.
