[NX-2170] Macros in shell notification channel are not resolved

[netxms-migration-bot]

1. E.g. shell notification channel has the following configuration:
   Command=/bin/bash -c "/bin/echo ${recipient} ${text} >> /tmp/file.txt"

Executing tools->send notification produces empty line into the file. Happens on 3.9.334 under Ubuntu 18.04.

2. Also in master built with sanitizer:
