Replace an inappropriate test expression that is always evaluating to true

[munahaf]

In file: rapiddns.py, the comparison of Collection length creates a logical short circuit; it will always evaluate to true. I suggested that the Collection length comparison should be done without creating a logical short circuit. The check is likely to be done only if the cells is of non-zero length. This is what I introduced.

Alpha-Omega is a project partnering with open source software project maintainers to systematically find new, as-yet-undiscovered vulnerabilities in open source code - and get them fixed – to improve global software supply chain security.

The bug is found by running the Intelligent Code Repair (iCR) tool by OpenRefactory and then manually triaging the results.
