Ref T210, cppcheck fixes

a) 23	performance	useInitializationList	false	Variable 'm_artifactsPilotClient' is assigned in constructor body. Consider performing initialization in initialization list.
b) 33	performance	passedByValue	false	Function parameter 'il' should be passed by reference.

a) is clear, but b) seems to be wrong, hidden by "cppcheck-suppress"
