There are multiple types of Identification Numbers in Romania and if you invoice
to a natural person, you are also required to send an electronic invoice.
Thus, we will add a check to allow the two TIN numbers that needs to be correct.
Example of valid tax number 'RO1234567897 or 'xyyzzaabbxxxx' or '9000xxxxxxxx'.
-Tin1: For xyyzzaabbxxxx, 'x' can be any number, 'y' is the two last digit of a
year (in the range 00…99), 'a' is a month, b is a day of the month, the number 8
and 9 are Country or district code
-Tin2: 9000xxxxxxxx, start with 9000 and then is filled by number (range 0 to 9)
Also stdum also checks the CUI or CIF (Romanian company identifier). So a number
like '123456897' will pass.
This commit will remove some test that are not relevant anymore since we can't
apply a vat number that don't follow the legal convention.
