Updated actual invocation formatting to show the values for reference…

[apollo2030]

When using verify to check for a specific invocation, the failure message was listing invocations of the method with the arguments using the objects ToString() method. The default implementation of the ToString() is to provide the full name which for more complex types is not very usefull - we a re more interested in the values of the properties of the complex type arguments.

What if you have provided ToString override just for this purpose?

[apollo2030]

I would have to do that for all the types the complex type consist of. Doing it here will prevent adding code to the types just for testing.

@apollo2030, I am closing this PR. The idea behind your proposal is a good one, but as per the comments above, this solution is too specific; a more generic mechanism / extension point would be preferable.

Thank you nevertheless for taking the time to prepare this! Perhaps we can base further work / discussion done on #84 on it so that your effort isn't completely lost!
