Correct the liquibase checksums for OpenMRS Provider Management module

Due to the changes done on provider management module to support PostgreSQL( PROV-105 ) and the recent liquibase update, we need to set the old checksum according to the checksum generated with OpenMRS-core before the liquibase update. That is we need to set the checksum generated with older version of Liquibase that was used. Correct the checksums.
