Views exposed form blocks now properly display their titles

Previously, when a views had an exposed filter, and "Exposed form in block" was turned on, the view had a title and the block was set to display the title, it would not display the title, and overriding the title in the block configuration would not display a title either.

For clarity, before this would not display a title:

This has now been fixed and these blocks with either Display title or Override title turned on will display the title views title or the overridden title respectively.

The update path updates existing views, disabling the label_display setting so as preserve expected previous functionality.

Actions for site builders / themers / developers:

• If you'd like to make use of this setting now, please make sure you were not already manually printing this on your templates so as to avoid displaying the block titles twice.
• If your site is using other means of inserting these blocks into the page, like page_manager/panels, make sure to revisit this setting so as to prevent presenting the titles twice.
