Fix specs in Ruby 1.9.3
Fix specs in Ruby 1.9.3

In 1.9.3 lambdas apparently complain when they recieve a different
number of parameters than they are supposed to. This was the case with
two lambdas passed to the "log" matcher which raised the following
exception when called:

  ArgumentError: wrong number of arguments (1 for 0)

Adding dummy parameters fixed that.
