[FIX] base: fix the customer search by vat number

Steps to follow to reproduce the bug:
-Go to sales
-Add a vat number with a '-' like: "123456789-5" to any customer
-Create a new SO
-Search the customer by entering their VAT number

Problem :
When the VAT number contains the character '-' you cannot find the customer with his VAT number.
The problem is the same if the vat number contains a '.'
Because, the "_name_search" method before creating the query to search clients by VAT number, removes all the special characters from user input

Solution :
Do not remove the characters '-' and '.' from the user input for the customer search by vat number.
