CLI 2.1.4: F# only templates get usage displayed when --language option is not passed explicitly

The same works fine with dotnet CLI 2.1.3

When creating project in dotnet CLI 2.1.4 from SAFE template, only usage is displayed:

λ dotnet new -i SAFE.Template

Apparently, passing --language F# does the job - this template is F#-only so this parameter should not be required.

[mlorbetske]

I believe this is related to #1373 (fixed in #1375) where if the template doesn't have a language that matches the "default" (C#) that the language must be explicitly passed. In this case, dotnet new SAFE -lang F# should work.

right, closing then and waiting for .net core 2.1.0 runtime release
thanks
