Fixed cache warmup of paths which contain back-slashes

From #8781

"
At this step in the warmup process there is a string replacement made, but paths with backslashes
are written into the cache file as something like `C:\\path\\to\\cache/pro_/...` but the str_replace
searches for the plain string `C:\path\to\cache/pro_/...`, which produces no matches.

The fix solves this by using var_export to escape the search (and replace) paths so they match the
format originally output into the cache file.

The `PropelTypeGuesser` did not match OneToMany relations properly. For example if you have a `Author` class with `Comments` attributes the guesser would guess "Comment" instead of "Comments".

I added some tests to ensure the non regression.
