WCPS1.5_Throw server GRPC exception when spatial domains are incompatible

[Bang Pham Huu]

WCPS query which multiple a coverage with another different size coverage

for c in (eobstest) return encode(
count(c[Lat(20.5:35.1),t(0:0), Long(10.5:75.3)]
 * c[Lat(20.5:35.1),t(0:20), Long(10.5:75.3)] = (8)
), "csv")

with WCPS 1.0 will throw an exception

<ows:ExceptionText>

</ows:Exception>

while WCPS 1.5 will have error in GRPC and should use same exception as WCPS 1.0.
