Bug 36321: Problem when dateexpiry in BorrowerUnwantedField

hen dateexpiry is in BorrowerUnwantedField it is hidden in patron edition form.
The problem is when editing an existing patron the value is re-computed with category settings, as if it where empty.

This comes from all fields in BorrowerUnwantedField beeing removed from %newdata in memberentry.pl.
Whe must skip dateexpiry.

Test plan :
1) Be sure dateexpiry is not in BorrowerUnwantedField
2) Define a patron category with enrollment period 12 month
3) Create a new patron in this category
4) Its expiration date is in now + 12 month
5) Edit the patron category to set enrollment period 6 month
6) Add dateexpiry in BorrowerUnwantedField
7) Edit the patron and save
=> Without patch the expiration date is changed to now + 6 month
=> With patch the exporation date is unchanged
