.less extension in @import is not optional in watch mode under some file structures

Which version are you using (less-watch-compiler --version to find out)? 1.14.6

Is the issue reproducible after updating to the latest version ( npm update less-watch-compiler)? yes

Describe the bug The LESS docs say that the .less extension is optional on imports.

But less-watch-compiler will throw an exception when it encounters such imports under very specific circumstances:

less-watch-compiler is ran on watch mode
there's another file in a nested folder

To Reproduce Steps to reproduce the behavior:

My folder setup is

.
├── css
│   └── site.css
├── less
│   ├── bem
│   │   └── block
│   │       └── file.less
│   ├── color.less
│   └── site.less

The less/bem/block/file.less and less/color.less files are empty. The content of less/site.less is @import "color";.

The command I ran is yarn less-watch-compiler less css site.less
Something went wrong... What is it?

Actual behavior less-watch-compiler throws an error:

~/s/repro (master|●7+2…) $ 
yarn less-watch-compiler less css site.less
yarn run v1.22.5
$ /home/filipesilva/sandbox/repro/node_modules/.bin/less-watch-compiler less css site.less

Expected behavior Should compile less files successfully.

Desktop (please complete the following information):

OS: Ubuntu 18.04.3 LTS

Additional context Using the --run-once flag will make it compile sucessfully.

Using the @import "color.less"; will make it compile sucessfully.

Removing the less/bem/block folder and leaving behind an empty less/bem folder will also make it compile sucessfully.
