Fix odd spacing on My PL page

[TurnerRiley]

In the "Joined PL Sections" section of the My PL page, if the user isn't in any sections then the spacing looks odd and leaves little room before the "Recommended for you" section below. So, this PR adds conditional formatting if the user isn't enrolled in any PL sections.

Previous "Joined PL Sections" with no sections (odd spacing)

Previous "Joined PL Sections" with sections (no change)

New "Joined PL Sections" with no sections (fixed spacing)

New "Joined PL Sections" with sections (no change)

Makes sense to me! I could go either way on adding this kind of logic in vs. outside of the render, so happy to approve as-is:)

Oh true, actually for consistency's-sake within the file, I'll move it to outside of the render!
