Description:
------------
We came across a bug when trying to get the last weekday of a month.
When we first setted a new date and afterwards modified it to get the last weekday of that month it
returns the last weekday of the month before the month given.

Test script:
---------------
$datetime = new DateTime()->setDate(2017, 12, 1);
var_dump($datetime->modify('last weekday this month');

Expected result:
----------------
DateTime {#12086
  +"date": "2017-12-30 00:00:00.000000",
  +"timezone_type": 3,
  +"timezone": "UTC",
}

Actual result:
--------------
DateTime {#12086
  +"date": "2017-11-30 00:00:00.000000",
  +"timezone_type": 3,
  +"timezone": "UTC",
}
