Fixed font awesome overleaf display issue

[jensschaefer]

Corrected fa-symbol for phone, not displayed correctly in overleaf.

Can you elaborate on 'not displayed correctly'?

Since mobile and phone are different icons, I don't really want to suddenly change it for someone who may be seeing it render correctly.

[jensschaefer]

I realized, I had misinterpreted the icon back in the day and introduced the phone icon for the sake of consistency.

With the phone icon the top bar looked more consistent.

The displayed icon looks more like mobile-alt. I think the actual mobile icon would fit here even better.

I think it maybe is a better fit, and it seems more visually consistent with the email icon, I'm just not crazy about suddenly changing that for anyone using it when they update (maybe they liked the old one).

How do you feel about that @posquit0, and versioning/'breaking changes' as it were in general?

If I can add my opinion, I prefer the icon proposed by @jensschaefer
On the other side, who doesn't like the default icon, is free to change it in the cls file.

[antenore]

To clarify it further. I'd merge this request and those that do not like it can always change the awesome-cv.cls file.

This has also come up in #418, and as I described there think I'm inclined to keep them the same but make it more easily editable as in #420.
