Stream: fixed segfault when using SSL certificates with variables. Similar to the previous change, a segmentation fault occurres when evaluating SSL certificates on a QUIC connection due to an uninitialized stream session. The fix is to adjust initializing the QUIC part of a connection until after it has session and variables initialized. Similarly, this appends logging error context for QUIC connections: - client 127.0.0.1:54749 connected to 127.0.0.1:8880 while handling frames - quic client timed out (60: Operation timed out) while handling quic input
