Display a warning if ther's no available preps

Fixes #4075

Still doesn't catch if the count of available preps is 0. In other words, if the number of unavailable preps is equal to the total count for a given prep under the cat num entered, the user should be made aware that no loan preparations can be added for that catalog number.

Edge case consideration:

For catalog numbers with multiple preparations, there could be variation in the availability status per preparation. We could indicate partial unavailability for that cat number in the response and then leave unavailable preps out of subsequent dialog?

I see,
the issue was that if a record didn't have preparations we had the "No preparations were found for the following" and nothing else even if one record would have been a part of "No preparations are available..."
I change the code to display both warnings if both present or just the relevant one.

@bronwyncombs ,
we warn the users of unavailable / missing prep for records but it's to them to remove the cat number or not.

This looks good. I think having the distinction between the preparation being available versus not found will make things more clear to the user.

Lets user know if selected records have no preparations. Looks good!
