Fix/1780 more robust fs

[Captainfl4me]

This pull request aims to fix this issue #1780. This issue is create by the libuv that sometimes can return nil type, therefore breaking the directory filter after a fs_readdir in the mason file system wrapper. To mitigate that I used the same fix as in this issue and use the fs_stat function if the type is not find by the fs_readdir function.
