Fix deletion of files without extension

[cbaconnier]

Tests are failing in Laravel apps when using fake images generated by UploadedFile::fake()->image('image.jpg') as the file will be generated internally by tmpfile() and will be named (E.g.) phpGoZkJ9

Currently, it looks if the path contains the filename, including the dot: phpGoZkJ9.

I changed it to match the full filename after the forward slash /
From my understanding, the $path will always have a forward slash (/) before the filename.

If there's a case where doesn't have a forward slash or uses double backslashes \\ (because Windows),I will happily update my PR to include corresponding scenarios and tests.

Thanks!

I'm wondering why is there a foreach and a check without the extension though.
Can a file have multiple extension without being itself a conversion or a responsive image?
