Fix issue preventing the Android Editor from displaying the project content

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.

(cherry picked from commit 30479543b0)
