Automatic function calling warning should not be displayed for helpers.default

[phillipskevin]

A warning is being (twice) displayed for "helpers" is being called as a function for switch statements:

{{#switch(foo)}}
  {{#case("bar")}}
  {{/case}}

  {{#default()}}
  {{/default}}
{{/switch}}

This happens when looking up helpers.case and helpers.default.

On this line:

can-stache-key/can-stache-key.js

Line 166 in 584c3ee

return options.proxyMethods !== false ? value.bind(prev) : value;

options.proxyMethods is false and so the function is returned without being called. There should not be a warning in this case.
