The current call uses the /domains end-point which lists all domains.
This only returns 100 domains at a time, so for long domain lists you
may not match and find the required ID.
Switch to using the search interface that only returns values matching
the requested domain. This will avoid missing results.

Closes: #2944
It seems the current code doesn't allow for removing the email address
from the contact field. This fixes that. This only removes the email
address if an explicit empty email address is specified on the command
line or in the account.conf file. If it is left unspecified on the
command line it still just uses whatever was configured in the
account.conf.
