[PATCH 13/39] tests/functional: don't try to wait for the empty string

[Alex Bennée]

From: Daniel P. Berrangé <berrange@redhat.com>

Telling exec_command_wand_wait_for_pattern to wait for the empty
string does not make any conceptual sense, as a check for empty
string will always succeed. It makes even less sense when followed
by a call to wait_for_console_pattern() with a real match.
