Create unit tests for todos effects

[tomastrajan]

Create tests for todos.effects.ts in todos.effects.spec.ts file either by following official ngrx testing guide or feel free to suggest any improvements.

Try to keep tests as independent as possible (eg minimize importing of various modules in setting up tests)

Feel free to check out Contributors Guide for useful tips and hints that help you get started.

Ah, the commit message referenced the issue but didn't contain keyword like closes or fixes so I have to close issue manually, anyway @terrystrachan thanks again!
