Update expected output of some test files when parallel query is enfo…

…rced

Update expected output of some test files in case of parallel query due to various reasons such as query plan changes, Order changes, etc. Also unblock these tests from parallel_query_jdbc_schedule file.

Reason for expected output diff in case of parallel query mode -

```
BABEL-2514 - order changes because of UNION
BABEL-2998 - order changes because of UNION
BABEL-328-vu-verify - order changes because of JOIN
TestSQLQueries - order changes because of JOIN

BABEL-1444 - We don't share state of the GUC "role" with parallel worker which will result in current_setting('role') to return none

BABEL-1363
BABEL-2843
BABEL-2844
BABEL-2902
BABEL-2903
BABEL-3248
BABEL-3295
BABEL-3513-vu-prepare
BABEL-3513-vu-verify
BABEL-4281
babel_collection
binary-index-vu-verify
cast_eliminate-vu-verify
babel_index_nulls_order-vu-verify
BABEL-4264

```
