Issues updating to version 2.1.2

I'm on Meteor 2.7.1 and when I try update this package, it always adds version 2.1.1. When I try to pin the version in `packages` with the line `aldeed:tabular@2.1.2` I get the output:

```
While selecting package versions:
error: No version of aldeed:tabular satisfies all constraints: @2.1.2, @=2.1.1
Constraints on package "aldeed:tabular":
* aldeed:tabular@2.1.2 <- top level
* aldeed:tabular@=2.1.1 <- top level
```
Is there some issue with the latest commit bumping the version to `2.1.2` that updates many of the dependency package versions?

Start by inspecting the package version and dependency declarations for aldeed:tabular, then reproduce the Meteor 2.7.1 update using the packages entry shown in the report. Determine why version 2.1.2 conflicts with the 2.1.1 constraint; done means Meteor can select 2.1.2 without retaining that conflicting constraint.
