Fix error prone bug pattern FloggerLogString

Some inappropriate usage of flogger logging makes error prone failing:

```error: [FloggerLogString] Arguments to log(String) must be
compile-time constants or parameters annotated with
@CompileTimeConstant. If possible, use Flogger's formatting log methods
instead.```
(see https://errorprone.info/bugpattern/FloggerFormatString)

This makes compilation fail.
Fix by using flogger formatting log method instead.
