Bug 36614: Restore 'phone' on the main patron search

Bug 36614: Restore 'phone' on the main patron search

It disappeared at some point (history is tricky here, I didn't manage to
track down what happened, it's a mess)

This patch adds a phone column after the "name and address" one. It's
hidden by default.
