Bug 29970: eval processing of MARC record to avoid crash

detail.pl displays a warning at the top of the page when a record contains
parsing errors

Bug 28734 and bug 11175 added additional parsing of the MARC record, but
they did not catch the thrown errors.

The existing pattern in the script is to eval responses to avoid crashing

This patch wraps the new calls in eval{}

To test:
1 - Find a record in the staff catalog
2 - Edit the record
3 - In the 520 notes field, add an ASCII escape character (27 decimal, 1b hex)
    On ubuntu Ctrl+Shift+u, then 1b, enter
4 - Save the record
5 - 500 Error
6 - Apply patch
7 - Reload
8 - The record displays with a warning at the top
