GH-162 - analyzing all params arguments

[tpodolak]

Improvements for #162

@dtchepak initial fix for #162 was not validating all params elements, so invalid cases like this

var substitute = NSubstitute.Substitute.For<Foo>(new object[] { 1, 1m });

were not detected. This PR aims to fix that problem
