Forward :context option from #save and #save!

Forward the `:context` option from `Base#save` and `Base#save!` to the
underlying `Validations#valid?` call.

This commit alos includes test coverage for directly calling
`Validations#valid?` with a `context` value, since that behavior wasn't
covered by tests elsewhere in the suite.
