storage_service: get_all_ranges: reserve enough space in ranges

Browse Source 
Commit bc5f6cf45d
added a reserve call to the `ranges` vector before
inserting all the returned token ranges into it.
However, that reservation is too small as we need
to express size+1 ranges for size tokens with
<unbound, token[0]> and <token[size-1], unbound>
ranges at the front and back, respectively.

Fixes #14849
