Add a fix for clear() on non-ref types by adding a missing 'var' annotation to the type signature

Browse source 
However, this fix won't take effect until a compiler bug (#4448) is fixed. Until then, the codebase functions identically to
how it did before this commit (calls to clear() fail to compile for Table/OrderedTable/CountTable as the argument is
immutable).
