fix(No Recommended): Enable blog/community carousel hiding in masonry views

[marcustyphoon]

Description

In masonry views, recommended blog/tag/community elements between posts are displayed differently and No Recommended fails to hide them. This fixes two of the three.

This currently doesn't include tag carousels since... I can't find one. I wrote "Check out these tags" in the linked issue, though, so obviously they exist. Based on staring at a bunch of minified javascript, I'd believe you if you told me the correct selector for them is or includes keyToCss('tagGrid'), but also if you did not say that. So.

Related/mostly resolves: #2322.

Testing steps

• Confirm that the "Hide recommended blogs between posts" and "Hide recommended communities between posts" No Recommended options still works on normal timelines.
• Confirm that the "Hide recommended blogs between posts" and "Hide recommended communities between posts" No Recommended options work on masonry-view timelines.

I would say I really wasn't sure what decisions to make to make this as robust as possible? Like, should the masonry selector be keyed on keyToCss('masonry') instead of a timeline selector? Should we be checking the title text? I dunno, I don't have a good grasp on this.
