read_versions is a function that attempts to read the current version
of the target system and the server version, but if there is an error
reading any of those values no action was performed so it was necessary
to validate these values wherever the function was being used,
duplicating code.
This commit adds a verification to make sure the current version of the
target system and the server version was able to be identified.
Closes#589
