#50968 - Single SQL Transaction for projectsornamespaces filter (#758)

* working for positive case

* changed to custom code

* removed comment

* added tests

* fixing ci error

* one more fix

* Update proxy_store tests for projectornamespace parsing.

Since we no longer need to execute a db query, and just return a filter,
we can drop a lot of code.

* added distinct back to conform with other queries

* one more fix
