Changed period in row evolution breaks graph/metric association (#14423)

* Changed period in row evolution breaks graph/metric association

fix #14208

worked for me, also with multi row evolution. Only known issue I found is if requesting eg first yearly row evolution which may have the `users` metric hidden, then switching to `day` period, and then the `users` metric is maybe supposed to become available but didn't. That should be quite edge case though.

* add class whether row is hidden

* Fixing couple regressions visible in ui tests.

* fix build + update comment

* tweak

* test tweak
