Subject: [PATCH] Fixed listDirectory()

[KONA] DF230714-00592

Issue: names returned via API can be invalid.
1. create many files in dir, 1-100.txt files
2. tizen.filesystem.listDirectory("documents", function(files) {f = files; console.log(files) }, function(e) { console.log(e) } )

issued list contains empty names/names with strange characters.

This fixes above problems.

[Verification] With above code, problem doesn't occur.
TCT passrate 100%.
