Test user visiting boards path with search params

What does this MR do?

This MR adds features specs that test users visiting board urls with search parameters.

Resolves #329411 (closed).

Why?

Most users use bookmarked boards urls which means they visit boards using urls with search parameters like this one

https://gitlab.com/groups/gitlab-org/plan-stage/-/boards/2668756?label_name[]=fresh%20label&group_by=epic

over a plain board url

https://gitlab.com/groups/gitlab-org/plan-stage/-/boards/2668756

Our feature specs currently do not take this crucial point into account only using plain board paths when visiting boards.

Possible boards configuration

We also need to consider all issue boards configurations:

1. Project issue boards with/without epic swimlanes
2. Group issue boards with/without epic swimlanes
