Fixes #494.

@philipgough thanks for reporting, please have a look.

@brancz I think the "upstream" code for the testutil package is gone from KSM by now. So no action required there, I guess.

reflect.DeepEqual is not suitable for zero occurrences of repeated
proto messages. This changes the comparison to act on the string
representation of proto messages.

@beorn7 great thanks. That seems to fix the original bug which I had resolved by just using ToFloat64 function. However I also just noticed that the CollectAndCompare function does not seem to work with some other types either.

I can confirm at least a *HistogramVec, has the same behaviour where matching strings are reported unequal. Perhaps it is to do with the DeepEqual on the pointer?

I can update the original issue or open a new one. If the latter then this looks to have resolved the original problem 👍

With this PR, there is no DeepEqual anymore.
I'll merge this, and if you still see problems with this merged, please let me know.
