Description:
Using a paragraph style with the insert page break before setting enabled, and the with page style and page number settings enabled results in an incorrect total page count.

This result is visible in the page count in the UI, as well as when using the page count field in the document.

Steps to Reproduce:
1. Open a new blank document in Writer and enter two paragraphs of text.

2. Select the second paragraph, and open the Paragraph properties.

3. In the Text Flow tab under Breaks, enable the check boxes for "Insert", "With Page Style", and "Page number". Type is Page, Position is Before, Page Style is Default Style, and Page number is 1. (Page number check box is not present in LO 3.3.0)

Actual Results:
The page total count in the bottom left of the UI is now 3. Inserting Fields > Page Count also displays the count as 3.

Expected Results:
The page count should be 2.
