String translation index error

Hi,

There’s an undefined index error on the strings translation tab when viewing only one language.

I added the following to the Polylang_Admin file at line 237 and it fixed the issue:

if (empty($_POST['translation'][$language->name])) {
	continue;
}

Here’s the fix in patch form: https://cl.ly/code/3847153u0j3I

Thanks!
