[Fix] undefined index EuLoginUser group

[pidera]

This PR fixes an issue that throws a notice during login via de EU login portal.
An index groups is fetched from a received user, but this does not exists, and should be group instead.

This notice prevents a good login flow in a more strictly configured PHP environment.

Dear @pidera ,

Your proposal doesn't pass the tests yet but...

I've been working yesterday (see #15) on this issue and I will continue to work on it Monday, today I'm not available for this.

I just pushed the branch I was working on yesterday, could you please test it out and provide some feedback?

Thanks :-)

Hi @drupol,

Thanks for the quick response. I have tested the branch (#15) in our application, and this seems to solve the issues we were experiencing!

As the issue is more than just group/groups naming, and the solution with the combined arrays and getter fallback returns seems pretty solid, as far as I can see, the solution in your PR is the way to go.

Good news already 👍

I'll continue my work on this on Monday.
