Profile fixes

[evertton]

• Fixed update user language, when underline is a character in language selector

  • When the language "Portuguese (Brazil)" was selected, the prevent LFI regular expression removed the underline character, so whenever the user chose this language they ended up receiving English as a fallback.

    echo $inputData['language']; // portuguese_br
    
    // Prevent LFI.
    $inputData['language'] = preg_replace('/[^a-z]/', "", $inputData['language']);
    
    echo $inputData['language']; // portuguesebr

• Fixes timezone selection display in profile

  • The way the logic was before, the system timezone was always selected. When selecting "America/Maceio" timezone in the profile and saving, the next time it was displayed, "UTC" appeared again. It was necessary to choose the preferred timezone whenever making any edit.
