University theme ignores section name if title is not set

[2xsaiko]

Take e.g.

#slide(title: [Title 1], new-section: [Section 1])[
  #lorem(20)
]

#slide(new-section: [Section 2])[
  #lorem(20)
]

#slide(title: [Title 2])[
  #lorem(20)
]

Only the first and third slides will display section name, and the third slide will show up as Section 1.

Looking at the code, I can see that the new-section argument is entirely ignored if title is not set.

	if new-section != none {
	utils.register-section(new-section)
	}
