Timber throws an error on hostings that for security reason have the '/' directory not readable.

[tkfv]

When using this code:

$context = \Timber\Timber::get_context();
\Timber\Timber::render_string( $template, $context );

I get this error:

The "/" directory does not exist ("/"). 

#0 /home/pmd/public_html/wp-content/plugins/timber-library/vendor/twig/twig/src/Loader/FilesystemLoader.php(87): Twig\Loader\FilesystemLoader->addPath('/', '__main__') #1 /home/pmd/public_html/wp-content/plugins/timber-library/vendor/twig/twig/src/Loader/FilesystemLoader.php(45): Twig\Loader\FilesystemLoader->setPaths(Array) #2 /home/pmd/public_html/wp-content/plugins/timber-library/lib/Loader.php(149): Twig\Loader\FilesystemLoader->__construct(Array, '/') #3 /home/pmd/public_html/wp-content/plugins/timber-library/lib/Loader.php(159): Timber\Loader->get_loader() #4 /home/pmd/public_html/wp-content/plugins/timber-library/lib/Timber.php(364): Timber\Loader->get_twig()

Is there a way to workaround this?
