Description

RealTimeGet with Composite router throws NPE at slice resolution time making it unusable.
I would like to add a check and possibly return nothing instead of the NPE.

[c:content s:shard1 r:core_node3 x:content_shard1_replica_n1] 
o.a.s.h.RequestHandlerBase java.lang.NullPointerException: 
Cannot invoke "org.apache.solr.common.cloud.Slice.getName()" because "slice" is null => 
java.lang.NullPointerException: Cannot invoke "org.apache.solr.common.cloud.Slice.getName()" because "slice" is null

one workaround is to pass "route" param.
