Additional Fix for BUG#44030 - Error: (1500) Couldn't read the MAX(ID) autoinc

                               value from the index (PRIMARY)


With the fix for BUG#46760, we correctly flag the presence of row_type 
only when it's actually changed and enables the FAST ALTER TABLE which was
disabled with the BUG#39200.

So the changes made by BUG#46760 makes MySQL data dictionaries to be out of 
sync but they are handled already by InnoDB with this BUG#44030.

The test was originally written to handle this but we requested Innodb to
update the test as the data dictionaries were in sync after the fix for 
BUG#39200.

Adjusting the innodb-autoinc testcase as mentioned in the comments.

mysql-test/lib/mtr_cases.pm:
  Re-enable the innodb-autoinc test case for plugin as we have a common
  result file.

  Adjust the innodb-autoinc testcase as the patch for BUG#46760 enables the 
  FAST ALTER TABLE and makes the data dictonaries go out of sync. This is 
  expected in the testcase.
