Open a record having a chatter, edit a field, add an attachment, leave
the page. The discard warning popup in not shown.
When an attachment is added, it reloads the record to fetch the new
`attachment_message_count`. Reloading the view was discarding the
changes because the `keepChanges` option was not set and defaults to
`false`. The changes were discarded thus the internal `_isDirty` flag
evaluated to `false` thus the popup was not shown as nothing would have
been saved.
The option was set in another `attachment_message_count` reload already,
in `chatter.js@_openComposer`.
