stringByReplacingPercentEscapesUsingEncoding called twice

[coil-code]

Calling stringByReplacingPercentEscapesUsingEncoding twice can mangle string or return nil if original string contains '%' sign

1. LEOWebDAVParser _currentItem.href = [_currentString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

2. LEOWebDAVItem return [[href lastPathComponent] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

File with name, for example, "File%Name", results in displayName equal to nil.
