checkCommands: Null check operator used on a null value

[jagged91]

Describe the bug
When using the giphy command, the message '/giphy ' gets sent rather than showing the giphy preview as in previous versions. Exiting the chat screen and returning will show the giphy preview as expected.

What package are you using? What version?
stream_chat_flutter: ^2.0.0-nullsafety.7

What platform is it about?

• Android
• iOS
• Web
• Windows
• MacOS
• Linux

To Reproduce
Steps to reproduce the behavior:

1. Use the giphy chat command
2. Type a search term
3. Tap the search icon
4. See that instead of the preview, you see the text '/giphy ' rather than the preview.

Expected behavior
The giphy preview should show as soon as the search icon is tapped.
