Don't crash when opening templates via WebDAV

When loading a ODT template via HTTP, it crashes LO with an
lang::IllegalArgumentException in LockFileCommon::ResolveLinks.
This happens when closing the loaded template, as LO tries to
remove a not-existing lock. aDocURL at this point is empty, so
HasError() is true.

As stated in the comment, we don't need a lock for documents
created from templates, as this opens an internal copy of the
document, so don't mark the teplate document as locked.
