Fix versions storing attributes as nil while manually creating a version

[abhinav-shrivastava]

Fixes #1047

The @record.attribute_before_last_save(attr_name.to_s) is giving me nil but if I try @record.attribute_was('name') in my console it gives me the correct value of the record. Adding @record.attribute_in_database(attr_name.to_s) worked for me.

Hi Abhinav, are you still working on this? Want me to keep it open?

[jaredbeck]

This solution does pass the existing tests. Please:

• Fix the linter offense
• Add at least one new test specific to Manually creating a version saves the object with nil attributes #1047
• Add an entry to the changelog under 9.0.0 -> Fixed

Thanks!
