Undefined function ccache_update() since latest updates to tt-rss code

Since the latest updates to the tt-rss code I'm getting this error about an undefined function. I'm not sure if this function used to be part of tt-rss and was deleted? It doesn't appear to be part of PHP.

Hi @matt-xtaz good tip, but ccache::ccache_update() doesent exists I used CCache::update() instead, and it seems to work: https://tt-rss.org/fox/tt-rss/blob/master/classes/ccache.php#L95

Ahhhh. Interesting. What I said worked fine for me!? I wonder if something in PHP 7.1.4 is mapping it. You're right though it looks like it should be ccache::update(). That also works for me. I'll redo the pull request.
