Fix Liquibase errors with Platform 2.7.0

[wikumChamith]

We have updated the Liquibase version of OpenMRS core to 4.28.0 on Platform 2.7.0. This update has caused the following issue with openmrs-module-appointments

org.openmrs.module.ModuleException: Unable to update data model using liquibase.xml. Module: Bahmni Appointment Scheduling

Caused by: liquibase.exception.LiquibaseException: java.lang.RuntimeException: liquibase.exception.UnexpectedLiquibaseException: java.io.FileNotFoundException: The file patientPastAppointments.sql was not found in the configured search path:

To mitigate the error this embedded SQL scripts into the liquibase.xml . We have done similar on openmrs-module-bedmanagement and openmrs-module-cohort.
