Bug 7878 - When duplicating a patron too many fields carrying over

When duplicating a patron the resulting entry form contains the data
from the original patron in the following fields: Other names, Initials,
Gender, OPAC note, Staff note, and expiration date. These should be
blank for a new duplicated patron. This patch corrects this.

To test, locate or create a patron record which contains data in the
fields listed above. Duplicate that patron and confirm that those fields
are blank in the resulting patron entry form.

Confirm also that editing an existing patron with data in those fields
works correctly.
