Move update from before to after_update

[straydogstudio]

All tests pass, with one new test. This seemed a little too easy, so perhaps it should be tested by a few people. I will use it and comment back here on any problems.

Line 734 in tests/unit/model_tests.rb had to be changed because line 728 now creates a version within the expected range.

This behavior should probably be added to the create event too.

I'll see what I can do with the failed travis build. It's a bit odd, since the values are apparently equal, but are not.

I've found a problem with protected attributes that doesn't show up in the test suite.

[straydogstudio]

The problem didn't show up because :created_at was made accessible in the dummy app initializer, so the test suite passed while my code didn't. I moved that to VersionConcern.

[straydogstudio]

Any thoughts on this one failed test on Travis CI? I installed jruby-18 and postgresql and all tests pass.

[straydogstudio]

Looks like Travis jruby-d18 with postgres has some transient problem. Last test succeeded.

Thanks so much for the PR. Sorry it's taken me so long to get to this, looks great!

@batter No worries! I know the dilemma... :{
