LP 1944602 Bootstrap Opac: Address alignment

Fixes the alignment of patron addresses in the Bootstap opac, if the
patron as more than one address.  Two addresses will now display
side-by-side in a row, except on smaller screens.

To test:

1. To fully test use patrons with one address, two addresses, and more than
two addresses.
2. Login as each patron and notice the mis-aligned addresses.
3. Apply the patch.
4. The addresses should now be displayed side-by-side, two per row. They
collapse to one per row on smaller screens.
5. Enable the 'Allow pending addresses' library setting.  The editable
address displays in the same space as it's non-editable display.
