JsonFactory.setStreamReadConstraints(StreamReadConstraints) fails to update "maxNameLength" for symbol tables

(note: off-shoot of a comment on #1001)

As reported by @denizk there is a problem in applying overrides for one of constraints:

JsonFactory.setStreamReadConstraints(StreamReadConstraints.builder().maxNameLength(100_000).build());

does not update symbol table set by:

JsonFactory._rootCharSymbols = CharsToNameCanonicalizer.createRoot(this); 

and only Builder-based alternative works.
It should be possible to apply constraints with setStreamReadConstraints() too.
