Add a TODO
#875 Updated check in block method so that it picks up mobile numbers that are NULL as well as empty strings.
Previously, there would often be an empty string to represent a missing value, but since the move to Postgres these now tend to be NULLs.
#875 Update method in PostgresConnector so that it checks the database cursor, and returns an empty string if the row is NULL.
The app code expects an empty string to signify a missing value as that's how it was done with MongoDB.
#875 Rename number variable to alt_contact_text
#875 Update move and unblock methods so that they are checking for NULL mobile numbers as well as empty strings.
