search: Prevent the search box from enlarging the view

By default, the search filters widget calculates its
`minimumSizeHint` as the sum of its components' minimum widths.

This minimum width hint will scale up the widgets hierarchy,
finally imposing a minimum width to the contents view, which
in certain conditions can take the space from the side panels.

Let's set a minimum width hint of 0, so it is the filters widget
which always adapts to the available view size instead.
