Fix specifications locator to find feature files

[milkovsky]

This is my fix for the #1076 issue.
Looks like feature files were not discovered properly. I have extended the locator and iterator for this.

Before:

./bin/behat features/migrate/articles.feature
...
No specifications found at path(s) `features/migrate/articles.feature`. This might be because of incorrect paths configuration in your `suites`.

After:

./bin/behat features/migrate/articles.feature
...
1 scenario (1 passed)
2 steps (2 passed)

P.S. Tests\Behat\Gherkin\Loader\GherkinFileLoaderTest shows no errors.

Yeeeeiii

missing the type array

i imagine this to be quite slow for big projects. wondering if we can improve it somehow.

[milkovsky]

Not sure. In my case the $locator is an exact feature file path. In this case foreach will loop only 1 time.
In addiition I guess it will be as "slow" as the next foreach block in this file below.

Tests are failing. This patch seems to be duplicating features in some cases.

I don't think this is the right approach. It should be possible to fix this bug without changing the existing interfaces.

Before 08802b7 it all worked fine, so I expect the issue is related to normalising the path, rather than changing the logic of finding features.

Thank you for the feedback. I simply did not find another way to set the features property. I guess we can just add setFeatures() method or smth similar to the FeatureIterator.php.

Good to know. I've just installed behat a few days ago, I am not very familiar with the previous versions. That was a quick workaround from my side to get the tests working. Feel free to close this PR if you preffer a different approach.

Behat/Gherkin#129 is the fix for this, already since 2017
