JSON does not allow real line-breaks. If a field contains them and they are not escaped, a JSON parser will be unable to convert the stringified JSON back into an object.
This is clearly exemplified by the guarantor search, where a multi-line note on the guarantor's record will break the ability to select that guarantor.
Test Plan:
1) Create Patron A with a "Circulation note" that has multiple lines in it
2) Create Patron B
3) Attempt to set Patron A to be the guarantor for Patron B
4) Note selecting the patron does nothing
5) Apply this patch
6) Repeat step 3
7) Selecting the guarantor now works!
