Force reload of clocked headline before clock operations

Without this update, certain changes to the buffer would not be
reflected in the `self.clocked_headline` attribute. This could cause
changes such as the auto-clock-out of a previously clocked header to be
inserted in the wrong location, corrupting the file.
