Splat arguments to NoStepMatch#format_args to avoid "wrong number of arguments (0 for 1) (ArgumentError)"

I ran into this: https://github.com/mdsol/bilgerat/issues/1

The problem is that the second argument to ```step_name()``` can be a a StepMatch or a NoStepMatch.  If it is a StepMatch I don't want to pass any arguments and just rely on the default format.  The problem is that if I don't pass any arguments to NoStepMatch#format_args I get an ArgumentError.  This patch splats the arguments to NoStepMatch#format_args to avoid ArgumentErrors. 

Test regression
