Android: Don't skip first file in assets entry list

We're using AAssetDir_getNextFileName() to verify that the
directory exists and has content, and this moves the
current file pointer to the second file in the dir, so
we need to reset the pointer before iterating to populate
the entry list.

[ChangeLog][Android] Fixed QDir::entryList() for assets
scheme to no longer skip the first file in the directory.
