Title: [L5] updated_at timestamp is already updated in Model::performUpdate

updated_at column is updated twice, first time in Model::performUpdate and second time in Eloquent\Builder::update.

Next, this pull request #5840 doesn't make a sense because column will be however updated in Eloquent\Builder.
