Sqlite's lack of an 'ALTER TABLE CHANGE' statement has prevented echo from supporting sqlite, and by relation has prevented Echo's unit tests from running within the foundations jenkins CI environment. This patch detects if the database is currently an sqlite database and applies a specially formulated patch that performs a rename/copy/delete operation to get the equivilient of an 'ALTER TABLE CHANGE' command. Additionally renames one index to have a more unique echo-specific name. Bug: 41987 Change-Id: I9b6468221ba6fe501b15c563f3301694262eec65
