This change fixes the `plan_expand_hypertable` test, which was broken and never ran the output comparison due to prematurely ending in an uncaught error. The test appeared to succeeded, however, since also the broken test "expected" files were committed to the repo. Fixing the test revealed that the query output with our optimizations enabled is incorrect for outer joins (i.e., the output from the query differed from regular PostgreSQL). Restriction clauses were too aggressively pushed down to outer relations, leading to chunk exclusion when it shouldn't happen. This incorrect behavior has also been fixed.
