Fix JS dependency tree

[Zodiac1978]

The order of JS seems to be wrong, because the dependencies are not used correct:
https://github.com/roytanck/rt-plugin-report/blob/develop/rt-plugin-report.php#L182-L185

This is the status quo:

wp_enqueue_script( 'plugin-report-js', plugins_url( '/js/plugin-report.js', __FILE__ ), array( 'jquery', 'plugin-report-tablesort-js' ), self::PLUGIN_VERSION );
wp_enqueue_script( 'plugin-report-tablesort-js', plugins_url( '/js/tablesort.min.js', __FILE__ ), array( 'jquery' ), '5.3' );
wp_enqueue_script( 'plugin-report-tablesort-number-js', plugins_url( '/js/tablesort.number.min.js', __FILE__ ), array( 'plugin-report-tablesort-js' ), '5.3' );
wp_enqueue_script( 'plugin-report-tablesort-dotsep-js', plugins_url( '/js/tablesort.dotsep.min.js', __FILE__ ), array( 'plugin-report-tablesort-js' ), '5.3' );

But I think it would be better this way:

wp_enqueue_script( 'plugin-report-tablesort-js', plugins_url( '/js/tablesort.min.js', __FILE__ ), array( 'jquery' ), '5.3' );
wp_enqueue_script( 'plugin-report-tablesort-number-js', plugins_url( '/js/tablesort.number.min.js', __FILE__ ), array( 'plugin-report-tablesort-js' ), '5.3' );
wp_enqueue_script( 'plugin-report-tablesort-dotsep-js', plugins_url( '/js/tablesort.dotsep.min.js', __FILE__ ), array( 'plugin-report-tablesort-js' ), '5.3' );
wp_enqueue_script( 'plugin-report-js', plugins_url( '/js/plugin-report.js', __FILE__ ), array( 'plugin-report-tablesort-number-js', 'plugin-report-tablesort-dotsep-js' ), self::PLUGIN_VERSION );

Explanation:

• The tablesort JS needs jquery (this should be the first JS executed).
• The extensions for numbers and versions (dotsep) need the tablesort JS, but the order is not relevant, so they just need this dependency.
• The last one is our own JS, which needs the extensions to be loaded, therefore those two dependencies.

This fixes the order of JS. Without it, our JS is loaded before the extensions are loaded.
