(search) Fix searching tags with spaces

Summary:
Tags containing blank spaces were not handled properly in the search widget.
Now we enclose them in quotes and strip the quotes before setting them to the widget.

No artifacts when searching tags containing spaces
Added test cases to `bin/dolphinquerytest`
