Add Else Clause For Embed Doc

When open_doc or open_revs return an error, we set the doc value
to be an error message. This way we account for errors rather than
transform_row throwing a function_clause.

> The problem happen when following conditions are satisfied:
> - user uses [linked documents|http://wiki.apache.org/couchdb/Introduction_to_CouchDB_views#Linked_documents] feature i.e. view emits {_id: "other_doc_id"}
> - query has include_docs=true
> - one of the shards returns any error or times out
> In this case we would have case_clause error either
> - in [case fabric:open_doc|https://github.com/apache/couchdb-fabric/blob/master/src/fabric_view.erl#L171]
> - in [case fabric:open_revs|https://github.com/apache/couchdb-fabric/blob/master/src/fabric_view.erl#L179]
> This case_clause error propagates to [transform_row|https://github.com/apache/couchdb-fabric/blob/master/src/fabric_view.erl#L132] and fails there since transform_row doesn't have a clause to handle errors.
