Unsupported/experimental call to keys() of driver result in scalar context

[johannessen]

REST::Neo4p::Query->_wrap_statement_result() makes a call to Neo4j::Driver::Result->keys() in scalar context.

$self->{NAME} = $result->keys;

Calling keys() in scalar context is experimental. At present, it returns the number of columns in the result rather than an array reference – in other words, it now behaves like a Perl list variable.

I’m eager to hear feedback on scalar context behaviour, for the driver as well as for Neo4j::Types.

To call keys() in a stable way, use list context.
