Member edit form split into two

[dapolach]

• member edit form split into two:
  • {{host}}/members/1/editOwnMemberInfoForm => form for members to edit own info
  • {{host}}/members/1/editByAdminForm => form for admins to edit info about other members
• several bugfixes:
  • initial data loaded in "db" have correct format of birthday certificate number
  • ORIS proxy API doesn't respond with HTTP 500 when user is not found by reg num
  • advanced validations (birthday certificate number for CZ, at least one email/phone contact) doesn't respond with HTTP 500
