Handle fully flagged channels in simager (ASKAPSDP-1590)

I have added a quick fix for the problem caused by channels completely
flagged. The imager throws an exception and previously aborted the whole
program. Now the exception is caught and will result in channel still being
present in the cube, but just zero filled.
