Only Pascal casing seems to work for custom templates

[Loke Sonne]

Describe the bug
When I try to use anything other than Pascal-case for the files in my custom templates, they are not replaced.

To Reproduce
Steps to reproduce the behavior:

1. Create a custom template for component
2. name it template-name.tsx
3. Add the custom template in generate-react-cli.json
   "component": { "default": { "customTemplates": { "component": "./templates/template-name.tsx" },
4. Run the cli, e.g. npx generate-react-cli component MyComponent
5. The component file in the created component has not been changed from template.name.tsx
   Expected behavior
   The filename should be my-component.tsx but is template-name.tsx

Machine (please complete the following information):

• OS: [e.g. macOS Mojave]
• Node Version [e.g. v10.16.1]

This and also the folder name should respect the same case sensitivity as the command for example:

npx generate-react-cli component demo should generate a folder called demo not Demo

Nope, it still doesn't work that way.
