[TIMOB-1474] Incorrectly adding percent escapes to URL with a custom port number

This is on iOS.

say I have a url 'http://localhost:3000/login', it'll get escaped wrongly and fail:

[ERROR] Error loading: , Error: Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found." UserInfo=0x7c4c830 {NSErrorFailingURLStringKey=https://localhost%3a3000/login, NSErrorFailingURLKey=https://localhost%3a3000/login, NSLocalizedDescription=A server with the specified hostname could not be found., NSUnderlyingError=0x7c4e470 "A server with the specified hostname could not be found."}

I removed the : from the usage of CFURLCreateStringByAddingPercentEscapes in TiUtils.m and NetworkModule.m temporarily for my purposes, though I suppose it does need to be escaped, just not in that part of the URL.
