[FIX] web: reload view when pressing enter in search bar

Before the control panel refactoring, whenever a user pressed ENTER in
the search bar (with no text), the current view was reloaded.  This
untested behaviour was changed (not on purpose) with that refactoring:
instead of reloading, the search view add a useless filter in the list
of facets.

We restore the previous behaviour in this commit.
