generate:subentry command fails if prompt has uppercase character.

[sayinserdar]

First of all great tool. Just what I needed. 🥳

Here is the problem whenever I try to run
ng g ng-samurai:generate-subentry
with lowercase, everything works perfectly fine.
However, if I somehow include an uppercase character it throws this error

Could not find an NgModule. Use the skip-import option to skip importing in NgModule.
I tried to set the --skip-import flag but no help
Here is a series of examples I tried.

If I can find some time and identify the problem. I'll try to open up a PR too. ✌️
