fix indentation of multiline log.exception() invocations

Commit f107e39989 ("Switch to more traditional logging structure",
2019-06-17) replaced "logging.exception" with "log.exception", effectively
shifting the argument lists 4 characters to the left. The second and
further lines of multiline invocations were not accordingly unindented,
however, which ended up setting a suboptimal precedent as well. Unindent
those lines now.
