[ObsUx][Infra] Unskip and try to fix hosts view test (elastic#197861)

Closes elastic#191806

The parts of the unskipped test were fixed here - the only case I
couldn't find the reason for failing after unskipping it is `should have
an option to open the chart in lens` - for some reason, the whole menu
is gone when checking the CI and I couldn't reproduce that so this will
be the only skipped part so we can at least have all the other `Hosts
view` tests
