Fix input icon being hidden on input focus

Both the datepicker and password fields have an assoicated icon. When
the input element receives focus the associated icons are hidden. This
is caused by a z-index issue and was a bug created when fixing another
bug that caused the datepicker icon from rendering above the table
batch actions toolbar.

Both bugs have been resolved with this patchset.
