[PATCH] http-fetch: invoke trace2_cmd_name()

ee4512ed48 ("trace2: create new combined trace facility", 2019-02-
22) introduced trace2_cmd_name() and taught both the Git built-ins and
some non-built-ins to use it. However, http-fetch was not one of them
(perhaps due to its low usage at the time).

Teach http-fetch to invoke this function. After this patch, this
function will be invoked right after argument parsing, just like in
remote-curl.c.

This was discovered at $DAYJOB after we noticed that there were command
names missing in the trace whenever a user did a fetch that involved
packfile offloading.
