Reason for revert:
This caused a compile failure on iOS bots.

Original issue's description:
> QUIC - Deleted disable_loading_server_info_for_new_servers field trial.
> Changed the code not to load server config if there is no alternative
> protocol entry for QUIC. During our experiments, we found that
> disable_loading_server_info_for_new_servers being set to true has
> reduced the latency until crypto handshake completion.
>
> This is a revert of https://codereview.chromium.org/811073004/
>
> We check for alternative protocols only if there is a http_server_properties_ object.

Change in
https://codereview.chromium.org/858323002/diff/40001/net/quic/quic_stream_fac...

has "....bool, bool, bool, int, float, bool,..."
but the above error line says "...bool, bool, bool, int, bool,float, bool,..."

Wondering if the bot had issues. This CL passed CQ and it builds on all
platforms. If the above error was true, it shouldn't have built on other
platforms also.

It compiled without issues today. Not sure why it failed before.
