Fix languages empty array

[GretaD]

When the language is forced an error occurs:

vue.runtime.esm.js:1888 TypeError: Cannot read property 'concat' of undefined
at a.userLanguage (UserRowMixin.js:125)
at hn.get (vue.runtime.esm.js:4479)
at hn.evaluate (vue.runtime.esm.js:4584)
at a.userLanguage (vue.runtime.esm.js:4836)
at a.<anonymous> (UserRowSimple.vue?fb94:1)

this happens because the forcedLanguage returns empty array.
Should be backported to 18 too

• Doesn't work for me, using 'force_language' => 'fr', show en

Doesn't work for me, using 'force_language' => 'fr', show en

hmm, do we need to change also here?

server/apps/settings/lib/Settings/Personal/PersonalInfo.php

Lines 192 to 198 in b569f3c

	* @param IUser $user
	* @return array

	privatefunctiongetLanguages(IUser$user) {
	$forceLanguage = $this->config->getSystemValue('force_language', false);
	if($forceLanguage !== false) {
	return [];
