Simplify some logic in CreateReplicationSlot() 

This refactoring reduces the code in charge of creating replication
slots from two "if" block to a single one, making it slightly cleaner.

This change is possible since 1d04a59be3, that has removed the
intermediate code that existed between the two "if" blocks in charge of
initializing the output message buffer.
