Moved grunt.log.ok to after reporterOutput is written

...so that we dont get malformed xml-output.

While running inlinelint on TeamCity with attached xml-parser we noticed that builds kept getting red since the 'jslint' output-xml was malformed (but only when no errors were found). 

Tracked it to have to do with the reset of the reporter in *wrapReporter* which has the consequence of evaluating *jshint.usingGruntReporter* to true inside the lint-callback.

Moving the output to after eventual output has been written changes nothing of the behaviour.

(and THANKS for an awesome plugin!)
