Fix issue preventing the Android Editor from displaying the project content

Browse source 
The issue was causing by a bug within the logic for `FileAccessFilesystemJAndroid#eof_reached()` causing that value to remain false after the eof was reached.
This in turn caused an infinite loop in the file scanner preventing the project's content from showing up.
