This makes it a lot easier to understand what went wrong when a test fails. This fixes proper-testing#131.
This was found by a dialyzer run: https://travis-ci.org/manopapad/proper/jobs/188348558 dialyzer -n -nn --plt .plt/proper_plt -Wunmatched_returns ebin

changed the title
Instead of testing methods on the erlang module, test proxies for them on ?MODULE so it's easy to replace them with buggy versions and see if the bugs are found. Also the error messages have been improved, comparing what happened to what was meant to happen.
This makes it a bit more challenging for PropEr to find bugs since it has less information to go on, so it makes for a slightly more interesting example. The change made it necessary to change the precondition for get/1 to always return true since we need to be able to get keys that should be undefined to detect if the erase function is no longer working.
