support names with more than 2 components when going to create patient page

when entering a patient's name with 4 parts on the find/create patient page, the name is truncated. on the next page it will only show the first and one last name.

for example, if entering "jose luis lopez ortega", the next page will display GIVEN: jose MIDDLE: <blank> LAST: luis.

however, the address bar displays all names:
...openmrs/admin/patients/newPatient.form?addName=jose+luis+lopez+ortega&addBirthdate=&addAge=12&addGender=M
