contentFor behavior changed

[stanislas-m]

contentFor helper behavior changed between versions v3.6.3 (the one gobuffalo.io uses now) and the latest version v3.6.8.

Before the upgrade, I used the helper like that:

<% contentFor("javascripts") { %>
    <%= javascriptTag("forums.js") %>
<% } %>

Now, I need to use the output version (with the =):

<%= contentFor("javascripts") { %>
    <%= javascriptTag("forums.js") %>
<% } %>

Since <%= is for output matters, contentsFor should use the <% version: it's only a setter.

It works when I use <% contentFor("javascripts") { %> and <%= contentOf("javascripts") { %> in the same template file (application.html), but not when the contentFor is in a partial or in the contents (the yielded part).
