ACT MSSQL Phenotype 4 missing placeholder on patient_dimension for @cdmDatabaseSchema

When updating to phenotype 4, find-replace fails to assign a schema to patient_dimension at line 446 because it lacks the placeholder @cdmDatabaseSchema.

This can cause downstream errors, if the user running the extraction has a default schema other than dbo (or w/e the @cdmDatabaseSchema should be for that site).
