use coalesce instead of join

[askazakov]

simplify template.json

Templates were updated in #2338. Is this still relevant? Also, what does coalesce do? I'm not familiar with the templates. @askazakov cc @YegorStepanov

Yes, it is still relevant. It's nothing but refactoring. Try to do a little bit more clean code.

Docs for coalesce is here https://github.com/dotnet/templating/wiki/Available-Symbols-Generators#coalesce (in short coalesce behaves like the C# ?? operator)

pr logic is something like

• framework either set via parameters or empty by default
• frameworkDefault depends only on app type (console or not)
• frameworkValue = framework ?? frameworkDefault (if framework is set then use it's value, otherwise use frameworkDefault accordingly app type)

@AndreyAkinshin Perhaps you could give this a look if @YegorStepanov isn't around?
