Description:
When moving a page to be a child of another page, and then moving it to be the last page in navigation, the page's position is not maintained when refreshing the browser.

Steps to Reproduce:
Description:
1. Create 3 pages on the default site in a clean Liferay DXP bundle so that there are 4 pages total.
2. Move the third page (example name "test2") using the side-bar navigation and make it a child of the top page.
3. Refresh browser.
4. Now take the same page (test2) and move it from being a child to being the bottom page.
5. Refresh browser.

Expected Results:
"test2" should be the last page in navigation.

Actual Results:
"test2" is one page above the last page in navigation.

Issue reproduced in branch.
NOTE: In branch this issue is only reproducible when using the second or third page, not when using the 4th / bottom page.

Could not test in master, the side bar navigation does not exist in master.
