fix: remove unnecessary isLoggingEnabled() checks (#420)

It appears that use of `isLoggingEnabled()` was erroneously copypasta'd
in many places. This PR updates its docstring to clarify that should
only be used to avoid constructing a potentially expensive docstring.
With this change, the only function that merits/uses this check is
`execCommand()`.
