Remove extra semicolon in insert_by_period materialization (#439)

* Remove extra semicolon in `insert_by_period` materialization.

`create_table_as()` generates a SQL statement that already ends with a semicolon, so the extra semicolon after a `create_table_as()` call in the `insert_by_period` materialization ends up being an empty SQL statement, and at least when using Snowflake this causes the dbt run to fail with a "cannot unpack non-iterable NoneType object" error.

* Update changelog for PR 439.
