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
