Loading Issue with Elementor and JSMin

[martinbkaiser]

I think there is a issue with the JSMin:minify(function) and Elementor. It seems to give a PHP error every once in awhile and that seems to stop the page from loading past the header.

[11-Jun-2019 18:08:09 UTC] PHP Fatal error: Uncaught Error: Call to undefined method JSMin::minify() in /www/wp-content/plugins/wp-property/lib/class_functions.php:2568

To Reproduce
Install Elementor and refresh the page a bunch of times, you will most likely see the page half load at least once.

Desktop (please complete the following information):

• OS: Windows
• Browser Chrome
• Version 74.0.3729.169

For a temporary fix I removed the JSMin::minify function:

wp-property/lib/class_functions.php - Line 2568
Changed:
$data = JSMin::minify($data);
to
$data = $data;
