fix(create-flutter-plugin): directory listing failed

[tomassasovsky]

Description
The command I ran:
very_good create ncnn --org-name=com.sportsvisio --desc="Native bridge to ncnn, a high-performance neural network inference framework optimized for the mobile platform" --template=flutter_plugin --web=false --linux=false --macos=false --windows=false --publishable

The output:

FileSystemException: Directory listing failed, path = 'C:\Users\Tomas\AppData\Local\Mason\Cache\bundled\very_good_flutter_plugin_0.2.1_5b74e6eea4904f8b209d5e5b0789ab77cb28c29b\__brick__\{{project_name.snakeCase()}}\{{#android}}{{project_name.snakeCase()}}_android{{\android}}\android\src\main\kotlin\{{org_name.pathCase()}}\*' (OS Error: The system cannot find the path specified.

Rollback to v0.8.5 fixes the issue, so it must've been added in v0.8.6, as it also breaks there.
It looks like what breaks everything is the update of mason in #579.
