Delete query failing if using secondary indexes - "DELETE alias collection1 not found in item"

Build : 7.1.0-2469
Last known good build : 7.1.0-2464

Steps to reproduce :
1. Setup a 1-node cluster with kv, index and query services.
2. Create a bucket, scope and collection - bucket1.scope1.collection1
3. Insert 1 doc -

insert into default:bucket1.scope1.collection1 (KEY, VALUE) VALUES ('doc1', {'val':1})

4. Create secondary index -

create index idx_val on default:bucket1.scope1.collection1(val)

5. Now delete doc

delete from default:bucket1.scope1.collection1 where val=1

This fails with error :

[

  {

    "code": 5080,

    "msg": "DELETE alias collection1 not found in item."

  }

]

6. Now drop the secondary index and create a primary index on the collection

create primary index on default:bucket1.scope1.collection1

7. Re-run the delete doc query. It works this time

delete from default:bucket1.scope1.collection1 where val=1

This is a regression caused due to the following commit :
