Search Builder searches using > 1 smart group where operator is equals is broken from 5.10.0
To reproduce
- Create 2 separate smart groups making sure that there is some contacts that overlap
- go into the search builder and add 2 clauses both groups and use the = operator and select each of the smart groups created in 1
- Observe it returns 0 results when it should return the overlap between the 2 smart groups
