SERVER-89833 made it so that mongos nodes are always syncronized after setting up an FSM test.

However, there are still a few pending places that have manual calls to the code as it was necessary to do before. We can safely remove those calls since they are duplicates of the normal execution now.

Here are the places:

• agg_lookup.js
• multi_statement_transaction_all_commands.js
• multi_statement_transaction_atomicity_isolation.js
• multi_statement_transaction_simple.js
