Post-commit fixes after the push for Bug#20837 et. al.

mysql-test/suite/innodb/r/innodb_information_schema.result:
  The transaction is in REPEATABLE READ, since the
  iso level was changed to SERIALIZABLE only for the 
  previous trx.
mysql-test/suite/innodb/t/innodb-semi-consistent.test:
  'commit' was missing from the original patch
mysql-test/t/parser.test:
  Moved the test for Bug#46527 to parser_not_embedded,
  since "disconnect default" isn't allowed with
  the embedded server.
mysql-test/t/parser_not_embedded.test:
  Moved the test for Bug#46527 to parser_not_embedded,
  since "disconnect default" isn't allowed with
  the embedded server.
