Fix namespace matching

[priyadi]

This fixes the bug where, for example, the namespace App\DomainService incorrectly gets matched using App\Domain

Resolves #253

Hi. Thanks for the PR.
Can you create a test for this?

I'll have a look to the failing PHPCS-Fixer ASAP, it doesnt seem an error from the changes, probably related to an update

I added a test, but I don't know if this is the proper way to do this. There don't seem to be existing tests specifically targeting selectors. However, I verified that it gives an error with the old code, and a success after the modification, as it should.

it seems to work 👍 that test is enough, I will try to improve the system in the future.

however, there are two failing steps in the CI:

• php-cs-fixer: it seems that now they catch FQCNs in the comments as well, and I want to test that FQCNs are catched. there seems to be a WIP way to ignore certain rules in some lines feat: [PoC] Support disabling PHP-CS-Fixer for single lines and rules PHP-CS-Fixer/PHP-CS-Fixer#7569
  For now, can you try locking the php-cs-fixer version so the maximum is the previous one? otherwise just apply it on local using the last version and I will revert to using the FQCN again in the future.
• phpunit on php 7 here: it seems "Namespace" is a reserved token word even inside a use statement on php 7 (they fixed it on php 8), can you rename the fixture namespace to something else? I will drop support for php 7 soon so I can rollback this workaround as well in the future.

It looks all OK now
