Bug 15059: Line break in html attribute in branchoverdues.tt

In circ/branchoverdues.tt, there is a line break inside href attribute.
This generates an attribute with a lot of spaces %20.

Test plan :
- at intranet go to ciculation module
- click on "Overdues with fines"
- look at links "Phone", "Notice" and "Considered lost"
=> Without patch the URL contains a lot of spaces
=> With patch the URL is correct
