NO-ISSUE: Fix issues in automate-no-registry-agent-tui.sh (#1782)

source agent/common.sh in e2e/agent-tui/utils.sh so that it can
find the getRendezvousIP function. This was missed in PR#1771.

The $VAR and $ip variables in pressKeys was not defined. Renamed
them to $node and $text as that appears to be what was originally
intended.
