This fixes a bug with the search box where, when it had a placeholder,
it would expand the width of the selection container because it was
too large. This bug was specifically caused by the search box not
factoring in the padding surrounding it when caclualting the width
it needed to be, which resulted in the search box extending
outside of the selection container. This bug was easy to notice if
your Select2 was set to have 100% width and if the container it was
held within was not a block element.
This fixes the bug by switching to using `width()` for calculating
the search width instead of using `innerWidth()`, which ignored the
surrounding padding.

This fixes a long-standing bug where if you tried to click in the
search box for a multiple select while there was text in it, the
dropdown would close and the text would be cleared. This caused
many unexpected issues, because it meant that you could only use
your keyboard to edit text within the search box.
This will still clear out the search field if you click within the
area of the selection which is not the search field. I'm not sure
if that is also unexpected behaviour, so for now I am going to
maintain it.

After we upgraded to QUnit 1.23.1, we gained support for
assert.expect(). This allows us to guard against any race conditions
within tests, because now expect() will be linked to the specific test
instead of the current running test.
This adds the test that ensures that the search focus is still
focused, even after the selection is updated (for whatever reason).
Note that we are not triggering the `change` event here, and are
instead just re-calling `update` on the selection adapter. This is
because we do not bind the `change` event in tests, so the selection
is never re-rendered and the tests will pass. The `update` method
is triggered during the `change` cycle anyway, so this has the
same effect while supporting cases where the selection is re-rendered
without the selected values changing.
