Check if we are using ExternalData extension

https://www.mediawiki.org/wiki/Extension:External_Data

It's yelding errors anyway:

<b>Notice</b>:  Did not find alias for special page 'GetData'. Perhaps no aliases are defined for it? [Called from SpecialPageFactory::getLocalNameFor in /var/www/public/wiki/includes/specialpage/SpecialPageFactory.php at line 691] in <b>/var/www/public/wiki/includes/debug/MWDebug.php</b> on line <b>311</b><br />

...if not, remove it.

Didn't find any references to its parser functions in hitchwiki/hitchwiki and hitchwiki/HWMap-extension

So I manually commented out the relevant line in public/wiki/composer.local on beta.hitchwiki.org to temporarily disable it. Let's see how it goes.

This extension gets currently installed, but is not loaded. Will drop it.
