Ignore binds payload with nil column in AR log subscriber

Some tests were raising the following error:

    Could not log "sql.active_record" event. NoMethodError: undefined method
    `type' for nil:NilClass`

Due to the way binds were being logged, the column info was considered
always present, but that is not true for some of the tests listed in the
issue.

Closes #8806.

Conflicts:

	activerecord/lib/active_record/log_subscriber.rb
	activerecord/test/cases/log_subscriber_test.rb

Conflict resolution:
- Revert ruby 1.9 style hash to support ruby 1.8
- Do not include 8f59ffc into 3-2-stable
