HACK: allow running parallel BTS_Tests.ConnHdlr components

Unfortunately, trxcon does not support handling more than one
connection in parallel.  If there is already one connection
established, it would reject all other connection attempts.

This causes an error in f_handler_init().  As a quick hack,
let's allow running BTS_Tests.ConnHdlr components without
establishing L1CTL connections at all.
