Re: Fix checker for GCA7FWE

Well it worked great until my reviewer tried it with his reviewing account, and then another's:

Goin' PostNet has used Project-GC to see if they qualified for this challenge and they did.
My furthest cache is 2300 mi away, and it had to be more than 3000 mi.
Goin' PostNet fulfills challenge ? (GCA7FWE) according to https://project-gc.com/Challenges/GCA7FWE/79386?u=Rkx0cmF2ZWxlcnM%3D&wpid=GCA7FWE

When it catches a non-qualifier, it gives a false response in km:
tela42499
My furthest cache is only 300 km away, and it had to be more than 3000 km.

Apologies, the script should be fixed now.

Works great! Thanks!
