Prevent double submits when creating channel collections

[bjester]

Desired behavior

We prevent accidental creation of multiple channel collections.

Current behavior

Clicking create to create a new collection may not respond right away

Value add

Prevents confusion by users when the creation doesn't complete immediately.
