Fixed small bug in note.from_lines

[s-cassidy]

If a note had frontmatter consisting of exactly one empty field, yaml.loads would return that field as a string rather than a table, causing an exception in note.from_lines.

Thanks for the PR @s-cassidy! Just one minor suggestion

[epwalsh]

How about just this:

Suggested change

	data = {data = nil}
	data = {}

[s-cassidy]

That's my poor Lua knowledge showing me up as I didn't realize nil table entries effectively don't exist. I've made the change if you want to just go with it. However, this is closer to what I was thinking

if type(data) == 'string' then
  local field = data
  field = field:gsub("^%s*(.-):?%s*$", "%1") 
  data = {}
  data[field] = {}
end

This way the following code still gets the name of the empty field (with trailing whitespace and : removed) with an empty table as the value.
