Don't add redundant quotes with escaped() in log messages.

The escaped() function and its kin already wrap their output in
quotes: there's no reason to do so twice.

I am _NOT_ making a corresponding change in calls that make the same
mistake in controller-related functions, however, due to the risk of
a compatibility break. :(

Closes #22723.
