BUG/MINOR: checks: Set missing id to the dummy checks frontend
The dummy frontend used to create the session of the tcp-checks is
initialized without identifier. However, it is required because this id may
be used without any guard, for instance in log-format string via "%f" or
when fe_name sample fetch is called. Thus, an unset id may lead to crashes.
This patch must be backported as far as 2.2.
