test(search): Add test case for baloo parsing model

Summary:
Adds a new test unit for the model which parses baloo search URLs
14/19 tests are set to `XFAIL` on current implementation, as they will be fixed in a final revision.

Supersedes D25135.

Depends on: D25257

Test Plan: `bin/dolphinquerytest`
