Fixes the issue with paths in groups section when codeception.yaml is not in the root of the project

• Fixes the issue with paths in groups section when codeception.yaml is not in the root of the project
• Add an ability to use absolute path for groups key in codeception.yaml

Example:

Imagine, custom codeception.yaml is located inside tests/_data folder.

We run codeception as

codecept -g x -c tests/_data/codeception.yaml

And we have the following group:

groups:
    x:
        ../../tests/unit/SomeTest.php

Such path is resolved to /path/to/project/tests/_data/../../tests/unit/SomeTest.php
and GroupManager.php can not match this path with the real path:

/path/to/project/tests/unit/SomeTest.php

Codeception/src/Codeception/Lib/GroupManager.php

Lines 116 to 118 in 014faba

	if ($filename == $testPattern) {
	$groups[] = $group;
	}

Applying realpath() solves the issue, because after that paths are the same and the code above successfully matches them.

Also, I've added an ability to use absolute paths:

groups:
    x:
        /path/to/project/tests/unit/SomeTest.php

We need it to integrate Codeception with Infection.

To be honest, have no idea how to fix the tests, because when I try to var_dump() anything in tests/unit/Codeception/Lib/GroupManagerTest.php, it's not being displayed to the console :|

I would appreciate any help / advice here.

@maks-rafalko try using codecept_debug instead of var_dump in tests and run codeception with -vv or -vvv flag to see it.

I think that these tests could be failing because they use made-up file names, so realfile returns false - https://github.com/Codeception/Codeception/blob/3.1/tests/unit/Codeception/Lib/GroupManagerTest.php#L15-L49

@Naktibalda I have resolved your comments and tests are green
