fix(migrations) ensure inserts are performed after schema agreement (#7667)

When bootstrapping a multi-node Apache Cassandra cluster, the CREATE
TABLE response from the coordinator node does guarantee that the schema
altering statement will result in schema agreement across the cluster.
This update moves the insert statement to occur after the CREATE TABLE
statement to ensure schema agreement occurs before executing the insert
statement.
