#1639: [raster] MapAlgebraExpr can't handle conditions

Comment(by dustymugs):
+1 for closing. There was a genuine issue with 1-raster ST_MapAlgebraExpr
where the returning value from the expression had to be a double
precision. Anything else being returned from the expression resulted in
NULL.
The output I'm seeing from my examples above look correct and are behaving
as expected. I'll try nicklas' attached example and see if the output
matches what the expression indicates.
