[BUG] Share Extension sometimes doesn't load image and sends empty msg

• Your Rocket.Chat Experimental app version: 4.4.0
• Your Rocket.Chat server version: 2.5.0
• Device (or Simulator) you're running with: Samsung s10e Android 10

I couldn't reproduce it every time, but it happened 20% of the time here.
Trying to share a screenshot from gallery causes this:

The app tried to load the image, but something happened.
Maybe we should show an error on these cases (or load it differently)

@diegolmello When this happens, if You press Send, does the attachment still get sent to recipient ?

[diegolmello]

Nope. An empty message is sent.

I think maybe fileInfo must be null, hence nothing is displayed on the above shown screen. I could not reproduce the issue, so I explicitly set fileInfo to null, and got the above empty screen when sharing an image. When I pressed Send, it loaded for a while and then the app closed. When I checked the channel, there was nothing there. But You also mentioned an empty message was sent, so I will try to reproduce that.
