Something in 0.4.8 broke my stuff

Describe the bug I have a DV table that shows upcoming brithdays (I think I got it from @Moonbase59). Since 0.4.8 it gives me the following error === Dataview: Every row during operation ‘where’ failed with an error; first 3:

        - Operator '+' is not supported for 'null' and 'number

===

To Reproduce This is the DV query being run…

## Upcoming birthDays
Here are the upcoming birthdays for the next 2 months (until =date(today) + dur(2 months)).
```dataview
TABLE birthDate as "DoB", choice(
date(today).month*100+date(today).day = birthDate.month*100+birthDate.day,(date(today)-birthDate).year,(date(today)-birthDate).year+1) as Age
FROM "People"
WHERE file.name != this.file.name and
choice(date(today).month*100+date(today).day > birthDate.month*100+birthDate.day,
(date(today).year+1)*10000 + birthDate.month*100 + birthDate.day,
date(today).year*10000 + birthDate.month*100 + birthDate.day) <= (date(today) + dur(2 months)).year*10000+(date(today) + dur(2 months)).month*100+(date(today) + dur(2 months)).day
SORT choice(
date(today).month*100+date(today).day > birthDate.month*100+birthDate.day,
(date(today).year+1)*10000 + birthDate.month*100 + birthDate.day,
date(today).year*10000 + birthDate.month*100 + birthDate.day)
```

Expected behavior Until 0.4.8 this query ran as expected. I reverted from 0.4.9, and 0.4.10, back to 0.4.7, and all is again as expected.

Upcoming release 0.4.20 finally fixes this annoying parsing error by correctly parsing emoji. Yay!
