Better class aliasing for compatibility with MediaWiki

I guess
class_alias( '\MediaWiki', '\MediaWiki\Actions\ActionEntryPoint' )
is a mistake, it should be
class_alias( '\ ActionEntryPoint', '\MediaWiki\Actions\ActionEntryPoint' )

And
if ( class_exists( \ClassName::class ) )
is a better and more secure choice to
if ( version_compare( MW_VERSION, '1.xy', '<' ) )
