Issue description

When installing my plugin GdUnit3 over the AssetLib it shows errors on the console.

This error occures 6 times
drivers/unix/file_access_unix.cpp:279 - Condition "!p_src" is true.

I find out this errors comming form files included in the plugin where have zero size.
e.g. \addons\gdUnit3\test\core\resources\copy_test\folder_a\file_a.txt

The error is only shown on MacOS, under Windows no errors are reported.

Files with zero length should not endup in a error.

Steps to reproduce

On MacOS

• open Godot with a fresh project
• go to AssetLib and install GdUnit3
• install by include all files

See console output
