Changed cost center input

[isabellafagioli]

Changed the component of the cost center dropdown (when adding a new user role) so that it can display all cost centers associated to the chosen organization before the user starts typing (requested by a client)

Test instructions:

• In B2B Customers > New > Add New add the role and organization and test the cost center dropdown;
• It should: suggest all cost centers related to that organization, allow you to type to search for a desired cost center, successfully clear the search.
