Describe the bug

When running a PHPCS compatibility check for PHP 7.4, the only thing CMB2 seems to report is this, in the file /cmb2/includes/CMB2_Base.php:

Since PHP 7.0, functions inspecting arguments, like func_get_args(), no longer report the original value as passed to a parameter, but will instead provide the current value. The parameter "$message" was used, and possibly changed (by reference), on line 416.

Steps to reproduce (I have confirmed I can reproduce this issue on the develop branch):

1. Set up PHPCompatibilityWP
2. In the root of WordPress where composer.json is, run the command ./vendor/bin/phpcs -p . --standard=PHPCompatibilityWP --extensions=php --runtime-set testVersion 7.3-

Possible Solution

Possibly, the solution is to move $args = func_get_args(); before the if ( is_numeric( $message ) ) { call.
