Channel Groups cannot save with Channel Filter on

[rbeckman-nextgen]

Issue:
With the Channel Filters on in the Channels view, you can drag and drop a channel into another group and cause the Save Group Changes button to appear.
Clicking on the button does not save, and prompts when trying to leave the view do not save

Steps to Reproduce:

• Create 2 channel groups
• In both groups, create at least 1 channel in each so that both groups appear when the channel filter is on
  ** Add a Label to each channel created
• Filter the channels such that you see both groups in the channels view
• Drag and drop any channel from one group to another
• Save Group Changes button should appear on the left under Group Tasks. Click on it

Expected Outcome:

• The channel groups get saved

Actual Outcome:

• Nothing seems to happen.
• The prompt from leaving the view also does not save
• Leaving the view and coming back, channel groups have not been edited

@pladesma this ticket should be reopened. It is still a bug.

I ran into it today on 4.0.1:

• Channels
• Search for channels with a filter for name
• Move one of the found channels to a different group
• Try to save the channel groups and it just sort of hangs
• Clear the filter
• Now you can assign/move and save channel groups

@rogin confirmed on 4.2.0. @joshm also said he has had the issue.

I suspect this will be tricky to solve because the channel groups are persisted as a complete set from the client to the server. When a filter is enabled the clients displayed set does not match the server set.
