In the actual tutorial app, we don't have <span> tags there --- I think it makes more sense to match the tutorial

@petebacondarwin should we change the tutorial to have span tags?

They get added in the phoncat project at step 4 - angular/angular-phonecat@749230e
We should probably just fix up steps 2 and 3

[petebacondarwin]

I added the <span> tags back into steps 2 and 3

[Starojitski]

The same is applicable to step 3, which is now the only step without spans around phone names
