BUG#20397: Crash at ALTER TABLE t1 engine = x; for partitioned table

Browse Source 
mysql-test/r/partition_error.result:
  New test cases
mysql-test/t/partition_error.test:
  New test cases
sql/sql_table.cc:
  ALTER TABLE t1 engine = x;
  will behave exactly like
  ALTER TABLE t1;
  See no reason why one should change handler to something not specified in query when
  there is already something one is attached to.
