The intention of the code was to clear sharding metadata
chunked_vector so that it doesn't bloat memory.
The type of c is `chunked_vector*`. Assigning `{}`
clears the pointer while the intended behavior was to reset the
`chunked_vector` instance. The original instance is left unmodified
with all its reserved space.
Because of this, the previous fix had no effect because token ranges
are stored entirely inline and popping them doesn't realease memory.
Fixes #4951
Tests:
- sstable_mutation_test (dev)
- manual using scylla binary on customer data on top of 2019.1.5
