If you request LogEventList to display the combination of 2 log types, and one of
those logs are restricted, will generate a warning, since it removes first entry of
array, but doesn't re-index the array, and subsequent code makes assumptions of the
form if ( count( $this->types ) $singleType = $this->types[0] (which doesn't work, as
first index is 1).

Thus cause array to be re-indexed if a $wgLogRestriction causes a log type to be removed.

Steps to reproduce the issue is make deletion log restricted, then view a (non-existent) user page.

Personally I think its kind of weird/wrong that if someone restricts both the move and delete log,
then viewing a non-existent will give "This page has been deleted, here's delete log:" followed by an
entry from *any* public log.
