      Bug #11751148 : show events shows events in other schema
      
      Issue:
      ------
      Due to prefix match, database like 'k' was matching with 'ka' and events of 'ka' we getting displayed for 'show event' of 'k'.
      
      Resolution:
      -----------
      Scan for listing of events in a schema is made to be done on exact match of database (schema) name instead of just prefix.
     @ mysql-test/r/events_bugs.result
        modified expected file with the expected results.
     @ mysql-test/t/events_bugs.test
        added a test case to reproduce the scenario.
     @ sql/event_db_repository.cc
        Scan for schema name is made to be done on exact db name match.

    modified:
      mysql-test/r/events_bugs.result
      mysql-test/t/events_bugs.test
      sql/event_db_repository.cc
