[ASTUnit] Fix a regression in cached completions

Summary:
After r345152 cached completions started adding namespaces after
nested name specifiers, e.g. in `some_name::^`

The CCC_Symbol indicates the completed item cannot be a namespace (it is
described as being "a type, a function or a variable" in the comments).

Therefore, 'nested specifier' completions should only be added from cache
when the context is CCC_SymbolOrNewName (which roughly seems to indicate
that a nested name specifier is allowed).
