Sending multiple images and then a message results in the message sending after the first image

When sending multiple images, you'd expect text send afterwards to appear after all of the images. However, it ends up sending right after the first image has uploaded.

## Steps to reproduce

1. Send multiple images at once (pick multiple images in the image picker)
2. Send some messages while they're uploading.
3. Look at another client and see that the messages are stuck between the uploaded images instead of at the end.
