WP_DEBUG_LOG not used properly

WP_DEBUG_LOG can be given a path to where the debug.log file can be stored but in a couple places in this plugin it doesn't respect that setting and puts it in the default location in the wp-content folder.

Start by locating the plugin's places that write debug.log and compare them with WordPress's WP_DEBUG_LOG path behavior. Done means every affected path respects a custom WP_DEBUG_LOG location instead of always writing under wp-content; no specific files or tests are named in the issue.
