Search/Selectors: Prevent unexpectedly removing a chip

One can close a chip by pressing the "X" close button on it. Prior to
this commit, one could also close a chip somewhat unexpectedly by
choosing an option from the Chip's dropdown. This commit removes any
"empty" options from the Chips which would lead to the Chip disappearing.

Example: Choosing "Any Rating" would remove the rating chip because it
would no longer act as a restriction on what the search should find. Now
the "Any Rating" option is not added to the Chip in the first place.
