plugin treeview: fix crash 

When the max_project_files is set to a higher value than the allowed
system maximum file descriptors, and opening a project directory that
causes dirmonitor to open a watch on a lot of files or directories, at
least on MacOSX it causes all system.* file functions to return nil
(for too many opened files) which breaks the project files scan.
