Intermittent failures at render time (cannot read property 'tags' of undefined

[liamcain]

Hi, sorry for filing all the tickets. I'm really just playing around and stress testing it a bit 😄

More than once I've run into the following stacktrace while switching to preview:

2index.html:9045 Uncaught (in promise) TypeError: Cannot read property 'tags' of undefined
    at TagIndex.eval (eval at <anonymous> (app.js:1), <anonymous>:9045:31)
    at step (eval at <anonymous> (app.js:1), <anonymous>:68:23)

Most recently it was while building the following dataview (not sure if it's related though):

task from ""
where file.day
sort file.day desc

Interesting. Looks like some files have no metadata in the Obsidian cache, so need to add a null check. Probably worth revisiting my index code and add some extra null safety pre-emptively. Will be fixed in 0.1.6.

I believe I've fixed most of these; it was an issue with how I parsed tags (I did it in different ways when a page was first indexed, and when it was later re-indexed due to a changed).
