Communication: Cannot create channels consecutively

[asliayk]

Describe the bug

After creating the first channel, attempting to create another one immediately does nothing. The channel is not created, and no error message is displayed. Refreshing the page is required to create a new channel.

To Reproduce

1. Go to Communication section of a course
2. Click on the plus button at the top of the sidebar
3. Create a channel.
4. After the channel is created, attempt to create another channel.
5. Notice that the second channel is not created.

Expected behavior

After creating the first channel, users should be able to immediately create additional channels without needing to refresh the page.
