Subject: [PATCH] test(material/chips): prevent unintentional test success

In 'MatChipInput' test, `MatInputModule` was not imported and
therefore the `matInput` directive was not interpreted.
If importing `MatInputModule` into the testing module,
the `matInput` directive gets applied and
the test 'MatChipInput basic behavior should be aria-required
if the list is required' would fail because of side effects
by setting the `aria-required` attribute. Obviously,
`matInput` does not remove the `aria-required` attribute,
while the chips implementation is doing so
(chips is interpreting false as null, while `matInput`
leaves 'false' as-is).
