Title: Address the ORA-00904 error with Rails 3.2.4.rc1

Tested with the Rails 3.2.4.rc1, test_remove_column_with_array_as_an_argument_is_deprecated got
an error with ORA-00904 error.

```ruby
1) Error:
test_remove_column_with_array_as_an_argument_is_deprecated(MigrationTest):
ActiveRecord::StatementInvalid: OCIError: ORA-00904: "[hat_name, hat_size]": invalid identifier: ALTER TABLE "HATS" DROP COLUMN "[hat_name, hat_size]"
```
All log file is available from [here](https://gist.github.com/2840310) .

It looks this commit is related with thie error (https://github.com/rails/rails/commit/02ca9151a043a4fefbb3f22edd05f0cd392fffaa) . I do not fully understand how new refactored remove_column method should be handled yet.
