Fixed log messages that are resulting in TypeError due to too many arguments

[Sai-Suraj-27]

What does this PR do?

FutureWarning should be used inside warnings.warn(), but at some places i see that it is used inside logging statements. So, I fixed them and some of the log statements have comma (,) between strings, which leads to considering them as multiple positional arguments, resulting in TypeErrors.
