When a remix fails it hangs and there's no see community button

[BryceLTaylor]

Expected Behavior

Remixes in the editor should succeed and if they don't they should stop trying after a while and leave the "see community" button.

Actual Behavior

When a remix fails it keeps showing you the alert that says it's trying to remix. During this time the "See community" button is not present.

Steps to Reproduce

Sign in on Scratch.ly
Navigate to the main page
Click "Chess Escape"
Click "See Inside"
Note: you should see the project in the editor
Click "Remix" in the top bar
Note: the green alert that says "remixing" stays there forever and there is no "see community" button.
It should probably time out and give some sort of error alert.

The inability to remix that project is already recorded in this issue: https://github.com/LLK/scratch-projects/issues/96

Operating System and Browser

e.g. Mac OS 10.11.6 Safari 10.0

The problem with Chess Escape was fixed (See https://github.com/LLK/scratch-projects/issues/96#issuecomment-450387734 , scratchfoundation/scratch-parser#50).

I can't seem to replicate the "hanging remix alert" issue, at least not using the connection settings in Chrome dev tools. It seems to give up after a while, and prompt you to try again or cancel.

This may be closable, though it's hard to know for sure that the problem is solved in all cases.
