Remove `gyanlakhwani` from avatar_usernames

[seeeturtle]

Since gyanlakhwani is hidden profile now, it is improper as test case for avatar_usernames.

[manu-chroma]

Actually the profile is not hidden, the person deactivated his facebook account.

[manu-chroma]

@seeeturtle can you add some other popular profile as replacement in the tests?

[gyanl]

Whoops, sorry guys - I'm off facebook for a while. We can use zuck from https://www.facebook.com/zuck, that's one account unlikely to go offline.

[seeeturtle]

sure.

[manu-chroma]

zuck is one of the edge case username. Min username length for facebook is 5.

Use username sheryl itself. She's the COO and won't delete her profile hopefully :sweat_smile:

[seeeturtle]

@manu-chroma , I'll use my username seeeturtle.

[seeeturtle]

hmm... weird... there is no og:image in my profile.

[seeeturtle]

oops, it seems my profile is hidden. I'll use sheryl

[seeeturtle]

All test pass except medium. @manu-chroma , are there any more problem?

[manu-chroma]

@seeeturtle awesome!
