Bug 26414: Unable to export Withdrawn status using CSV profile

When using CSV profiles to export MARC records, it is impossible to export the withdrawn status. I suspect it is because withdrawn is in 952$0 and 0 is considered null rather than an actual 0.

Test Plan :
1) Go to Tools > CSV profiles
2) Click on New CSV profile
3) Enter a profile name (ex. Simple record)
4) In the Profile MARC fields field enter the following (for MARC21)
245a|100a|952o|9520
5) Save your profile
6) Go to Search and search for something
7) Add a couple of things in your cart
8) Go to your cart
9) Click on Download and choose your CSV profile
10) Open the file and notice the 9520 column contains the whole of the 952 field and not just the withdrawn status
11) Apply patch
12) Redo steps 9) and 10)
