Special page name should be capitalized in alias file

[lokal-profil]

E.g.

$specialPageAliases['en'] = array(
    'Wikispeech' => array( 'Wikispeech' ),
);

instead of:

$specialPageAliases['en'] = array(
    'wikispeech' => array( 'wikispeech' ),
);

Otherwise mwext-testextension-hhvm gives the warning/notice: First alias 'wikispeech' for wikispeech conflicts with canonical alias for Wikispeech.
