Bug 26598: Display guarantee's fines on guarantor's details page

A new tab is added to the details page of a patron to show, in a table, the fines of the patron's guarantees. A warning appears in the "Guarantees" section of the patron to make it obvious that fines exists.

+ resolve a git merge conflict

To test:
1) Apply patch
2) Choose a patron that has guarantees and navigate to the patron's details page
3) If the guarantees don't have any fines, the display should be unchanged
4) Add fines to the guarantee
5) Go back to the guarantor's details page
    => A warning should appear in the "Guarantees" section with the total due
6) Clicking on the link accompanying the warning focuses on the new
"Guarantees' fines" tab containing a table of all guarantee's and their
fines.
