NEST - SearchRequest ignores default index

[Roemer]

When using a SearchRequest object without specifying an Index, the DefaultIndex defined in the ElasticClient is ignored and all indexes are being searched. But when using a SearchDescriptor without specifying an index, the DefaultIndex is used correctly.

@Roemer many kudos for catching this one.

SearchDescriptor() should default to /default-index/_search unless AllIndices / AllTypes / Indices / Types are explicitly stated.

SearchDescriptor<T> should default to /default-index-for-t/default-type-for-t/_search unless AllIndices / AllTypes / Indices / Types are explicitly stated.

I just pushed a fix for this 👍 for reporting.

Awesome fast handling, thanks!
