lib/drb/extservm.rb (service): do not return `false'
invoke_service_command may set entries in @servers to `false',
making it incompatible with the intended use of the
safe navigation operator.
This caused occasional DRb test failures, but they were hidden
with automatic retry.
[ruby-core:87524] [Bug #14856]
Fixes: r53111 ("use safe navigation operator")
