Description

Current Soundex Function presents errors in generating results for some specific cases, when we have a sequence of 2 equal numbers separated by 0 it ends up ignoring it, as it deletes the 0 before generating the entire Soundex

Example with errors:

Alice Ichabod   -> Correct return is A422 but the Soundex returned A421

Luke Garcia       -> Correct return is L226 but the Soundex returned  L262
