Can no longer compute dates

[irodionzaytsev]

As mentioned in this answer it used to be possible to use the following syntax: {{date-1w}}. Now it seems no longer possible. When I do this, it doesn't insert the previous week, it just treats this as plain text.

I think this commit is the issue: 7310566

It looks like the +/- templating works for every granularity except weekly templates.
