Current behavior:

When writing a spec if an interval is set with a delay argument equivalent to zero, then using the flush method will generate an infinite loop.

Expected behavior:

When running setInterval(..., 0); in the browser it is executed almost every tick, for mock the same behavior is expected.

Minimal reproduction of the problem with instructions:

1. Open the app.spec.js file
2. Uncomment the line with the flush method

Result: the browser's tab will crush due infinite loop.

Angular version: 1.6.4

Browser: all
