New cells use notebook default language instead of previous cell language

[jonsequitur]

When creating a new cell, the default language is the notebook's default language.

It is expected to be the same language as the previous cell, e.g. in the following screen shot in a notebook whose default language was set to C#, the second cell should be javascript.

Hi @jonsequitur

I couldn't repro this issue (animated gif below). Did I miss a step?

@ocallesp : You'd likely want to create a C# cell after the first js cell and then create a new cell after that. The 3rd cell should be C# and not js.

I updated the issue description to be hopefully a little clearer.

Assigned this issue to @brettfo since he already has a PR ready for review.
