Android: createTempDirectory() does not create a directory

Summary:
The Ti.Filesystem.createTempDirectory() method does not create the referenced directory by default on Android. It correctly returns a Ti.Filesystem.File object referencing a new directory, but the Titanium developer is forced to create it manually afterwards, which doesn't match iOS' behavior or what's implied by the method name.

Steps to reproduce:

1. Build and run the below on Android.
2. Notice in the log that "exists" returns false. (This is the bug.)

var tempDir = Ti.Filesystem.createTempDirectory();

console.log("@@@ nativePath: " + tempDir.nativePath);

console.log("@@@ exists: " + tempDir.exists());

Note:
Android should also be changed to create the temp directory under the Ti.Filesystem.tempDirectory like iOS. Currently, Android puts the temp directory in a radically different location that Titanium does not offer a directory constant for.

Work-Around:
You must create the directory manually like the below.

var tempDir = Ti.Filesystem.createTempDirectory();

if (OS_ANDROID) {

	tempDir.createDirectory();

}

console.log("@@@ exists: " + tempDir.exists());
