Title: Backport #8522, Keep index names when using  with sqlite3

This is a backport of #8522 to fix #3489

Conflicts:

activerecord/CHANGELOG.md
activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb
activerecord/test/cases/migration/rename_column_test.rb

The files looked quite different on `rails/3-2-stable` but the affected line is exactly the same. Also the tests have a different format.
