Don't delete meta files when pages are deleted, fixes FS#2301

As we need to keep all core meta files anyway (the only core file that
had been deleted but shouldn't be deleted is the .indexed file) and
plugins can keep care of their own metadata files using the
IO_WIKIPAGE_WRITE event there is no reason for using the expensive
metaFiles() function during the deletion of pages.
