Cannot Delete Channels from Channel Edit Page

[sairina]

Summary

Clicking "delete" from the upper right-hand corner of the Channel Edit page doesn't allow for user to delete the channel at all.

Note: Clicking "delete" from the Channel List page deletes the channel, but results in the following error in the console:

Uncaught (in promise) DexieError {_e: Error
    at getErrorWithStack (https://studio.learningequality.org/static/studio/channel_list-6ef0…, name: "PrematureCommitError", message: "Transaction committed too early. See http://bit.ly/2kdckMn", inner: null}
