Only reparse project if meson-info contents change
Currently there is a file watcher that reloads the project when the meson-info.json file changes. If the project fails to configure, kdevelop keeps attempting to reconfigure in a loop because the meson-info.json file keeps getting rewritten. This change makes it only reconfigure if the contents of the watched file are actually changed avoiding the loop.
