Booking refresh follow up work

A note: I figured out why switching to the booking Angular app appears to cause a full refresh. I threw that fix onto the collab/sandbergja/lp1816475_booking_followup branch

And another note: the date-select and datetime-select were using a material icon that messed up the buttons when served locally. I swapped it out for another icon that works better, and that's now also in that branch.

And another commit to ignore trailing whitespace in patron barcode fields

I added another commit to fix the unlocalized datetimes in the pull list.

The only item left is to add some validation to make sure that users don't create booking reservations in the past.

Validation added. All improvements available at collab/sandbergja/lp1816475_booking_followup

I believe this resolves all of the issues with the booking refresh from the 3.4 beta. Happy testing!

I've signed off on the current branch and pushed user/gmcharlt/lp1816475_booking_followup_signoff. My signoff branch includes a follow-up to align the start-time-after-end-time alert with the inputs for a (to me) cleaner appearance.

I see a couple issues with the presentation of form validation issues in the create reservation dialog, but they don't need to hold up this particular bug:

- the green bar that displays on the left side of the datetime inputs when a value is supplied (matching the required attribute) can be misleading if the value supplied is invalid (e.g., is in the past)
- datetime-select validation alerts are displayed only in the drop-down widget; perhaps they should be displayed before the datetime input for greater visibility

Pushed to master and rel_3_4. Thanks, Jane!
