Cached templates that no longer exist

[rkocman]

Version: 2.4.8

Bug Description

I am not really sure if this is a bug or a feature, but if you render some template with cache enabled and then you remove the source file, the cached version is still being used. I think that this depends on your interpretation of what it means for a cached template to be expired.

Steps To Reproduce

1. render some template with cache enabled
2. remove the source file
3. render the same path again

Expected Behavior

Exception 'missing template file'

Possible Solution

The function isExpired in Latte\Loaders\FileLoader is already being called, however, it only checks the modification time of the source file and not its existence. I can use my own FileLoader that fixes this, but why this isn't somehow possible in default?

Verified. When source.latte is removed and cached PHP file still exists, it is used even with $autoRefresh enabled.

In this case, FileLoader::isExpired() returns false, because filemtime() results to false which is always less than given timestamp.
