Stop SafeBuffer#clone_empty from issuing warnings

Logic in clone_empty method was dealing with old @dirty variable, which
has changed by @html_safe in this commit:
139963c

This was issuing a "not initialized variable" warning - related to:
#5237

The logic applied by this method is already handled by the [] override,
so there is no need to reset the variable here.
