[bf luis:generate:cs] Disparity with bf luis:generate:ts to try/catch errors #1050

Versions

What CLI version are you using.
4.10.1 or master branch

What Nodejs version are you using
12.14.1

What command-line interpreters are you using
bf luis:generate:cs

What OS are you using
Windows 10

Describe the bug

There is a disparity between the bf luis:generate:cs and the bf luis:generate:ts commands. This cause that the :cs is throwing a generic error because it's not catching correctly the error as they are not wrapped in a try/catch sentence like in the :ts.

To Reproduce

1. See async run() of bf luis:generate:cs.
2. See async run() of bf luis:generate:ts.
3. Check the differences of wrapping in a try/catch sentence.

Expected behavior

The command should throw the same error like bf luis:generate:ts, and not a generic one wrapping the process in a try/catch sentence.
