Deprecated Polylang function : $polylang->model->get_post_language()

Hi,

Running a search with Polylang 2.0.5 and Relevanssi 3.5.4 activated returns this message from the debugger :
Notice: get_post_language was called incorrectly in C:\mysite\wp-content\plugins\relevanssi\lib\common.php on line 26: the call to $polylang->model->get_post_language() has been deprecated in Polylang 1.8, use PLL()->model->post->get_language() instead. Error handler in C:\mysite\wp-content\plugins\polylang\include\model.php on line 620

Changing line 26 in \lib\common.php
from
if (PLL()->model->get_post_language($hit->ID)->slug == ICL_LANGUAGE_CODE) {
to
if (PLL()->model->post->get_language($hit->ID)->slug == ICL_LANGUAGE_CODE) {
works fine.

Just thought you should know.
(thx for the great plugin btw!)
