[FIX] web: Save search bar state to local storage
[FIX] web: Save search bar state to local storage

The state of the search bar (expanded or not) is supposed to be saved
into a local storage variable which is retrieved whenever loading a view
that has the search bar in it and it is expanded automatically if it was
done previously in any other view, this didn't happen previous to this
commit because the variable wasn't being set properly (missing key).
