Fix an error when move to a path containing spaces

[sung-eun]

URISyntaxException occurred when move destination path has spaces.

I removed URI.create(...) about destination url.
Also added test case for this case.

Caused by: java.net.URISyntaxException: Illegal character in path at index 120: http://demo.owncloud.org/remote.php/webdav/test8cec534b-73b9-4f45-89a6-e9f278359690/60fbf14d-5689-421e-a316-54754de220d8 blank test
