MgUnclassifiedException thrown by FdoISelect::Execute not being caught by MgMappingUtil::ExecuteFeatureQuery

[tonyfang]

In MgMappingUtil::ExecuteFeatureQuery? , the call to svcFeature->SelectFeatures? can throw an MgUnclassifiedException?. The try-catch was only catching MgFdoException?. Thus the exception would not get caught, and propagate up into the catch of MgMappingUtil::StylizeLayers?, which would result in an error log entry.

The fix is to change it to catch an MgException?. Then the MgUnclassifiedException? is caught. The next call to svcFeature->SelectFeatures? (using MgFeatureSpatialOperations::Intersects) succeeds.

I also noticed a similar call in MgMappingUtil::ExecuteRasterQuery?. We should make the same change there as well – to be consistent, and just in case an MgUnclassifiedException? occurs there too.
