Case: We have two paths. Template is in second.
After we load this template for the first time, we move
file from other location to the first one.
New template overlays the already loaded one - it would
match the same path.
Because we move file, its mtime may be older than mtime
of the already loaded one.
We should detect new file an reload template.
