Added test case for : chars in sequence

This is closer to the actual problem. The error message will look something like this
```

merging from the main fork.

loadConfig() is already called from constructor.

In PHP 8.0.1 (Ubuntu), it's not possible to execute any command as it would return this error:
Error: ReflectionMethod::__construct(): Argument cakephp#2 ($method) cannot be null when argument cakephp#1 ($objectOrMethod) is an object

Just add the fix to prevent empty value in hasMethod().
