Bug 17117: Patron personal details not displayed unless branch update request is enabled

In patron acount ("your personal details" tab, which serves as a form
for submitting update requests as well) it's not possible to display
some account details like expiration date etc., without enabling
the field for branch / library update requests too.

To reproduce:

1) set OPACPatronDetails to "Allow"
2) clear PatronSelfModificationBorrowerUnwantedField preference
- all possible fields in the update requests form are visible
in patron account, including some extra details (card number,
expiration date, category) in the "Library" section on top
3) put 'branchcode' in PatronSelfModificationBorrowerUnwantedField preference
4) the whole 'Library' section disappears

To test:

1) apply patch
2) put 'branchcode' in PatronSelfModificationBorrowerUnwantedField,
'Library' section should remain visible (sans branch selection option)
3) put 'branchcode|cardnumber|datexpiry|categorycode' in the same
preference, 'Library' section should now disappear
