Fix GHI 4041 Terrain Shader Crash (#4050)

Browse Source 
The terrain feature processor was crashing due to an invalid shader name.  The shader name has been fixed, but the feature processor has also been hardened so that it no longer crashes if a shader fails to load.
Also, while testing, this inadvertently exposed a second crash in EntitySerializer that occurs when components don't serialize in correctly.
