cancel() does not work in ngMock's $interval

[kseamon]

Calls to cancel in ngMock's $interval throw "TypeError: Cannot read property '$$intervalId' of undefined".

It tries to access the promise local variable outside of the scope in which it was declared.

This should be an easy fix for someone from the community looking for issues to help out with.

I'm someone from the community looking to help out. I'm looking into this!

[dluxemburg]

@kseamon were you passing a promise argument to cancel? I think it's looking for that and not the promise variable created inside $interval itself.

[kseamon]

@dluxemburg You're probably right. I'll have a look tomorrow.

[kseamon]

Yes, I was indeed passing undefined. @dluxemburg does correctly make the mock's behavior match up with the actual service, however.
