BUG/MINOR: trace: Test server existence for health-checks to get proxy

Email alerts are based on health-checks but with no server. Thus, in
__trace() function, responsible to write a trace message, we must be
prepared to have no server and thus no proxy.

This patch must be backported as far as 2.4.
