Comment 3 for bug 1924621

Here's a follow up branch:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1924621-hold-for-use-pref-name

1. Adds sign-off's to Gary's patch.

2. Adds a second patch to display the pref name in the banner along the top of the catalog page, "Placing hold for <patron pref name>". (Accessed from patron search -> select patron -> holds -> place hold).

Without the second patch, a scenario arises where 2 variations of the patron name are displayed on the same interface, which is confusing.
