No project templates in latest nightly

[cmeeren]

Project templates are missing from latest nightly (15.4.1.17111702). Here's the result of searching for "f#" in my New Project dialog - only Xamarin templates are found:

I think something in our recent pushes to master wiped them out for 15.4 installations - I can repro this on VS 15.4. @brettfo @KevinRansom any ideas?

We split them into a different vsix (to be in different workloads), so nightlies are replacing a vsix that contains them with one that doesn't. May need to tweak dogfooding instructions to include a set of vsixes to install, or make a nested hierarchical vsix.

(The latter tends to hit some bugs in auto-update though).

Weird that it would happen now, though. #3720 was merged into master more than a month ago, so I would have expected a bug like this to be reported a lot earlier than now.

NIghtlies will not have templates until dev VS2017.5 is released.

By-designing this, then. Bit of a shame, but given that we're fairly close to the 15.5 release + nightlies aren't officially supported it's not the end of the world
