Update DbView.php

Updates my previous pull request that checked Laravel version. It was failing because it was finding '5.2' string in the 5.5.2 Laravel version. This new PR makes use of PHP's built in version_compare function to compare versions rather than just doing a string compare. Anything L5.4 and up uses flushStateIfDoneRendering().
