Remove yaml Proc param parser test

I don't believe this test is exercising any explicit params_parser
behavior that the other two Proc tests aren't already doing.  Given
that we now know it's a bad idea to load user input via YAML.load,
somebody reading this test might get a dangerous idea about building
out a YAML params parser.

Fix `content_tag_for` with array html option.

It would embed array as string instead of joining it like `content_tag` does:

    content_tag(:td, class: ["foo", "bar"]){}
    #=> '<td class="foo bar"></td>'

Before:

    content_tag_for(:td, item, class: ["foo", "bar"]){}
    #=> '<td class="item [&quot;foo&quot;, &quot;bar&quot;]" id="item_1"></td>'

After:

    content_tag_for(:td, item, class: ["foo", "bar"]){}
    #=> '<td class="item foo bar" id="item_1"></td>'
