Force log when trace is enabled

Enable force logging for all log statements when a trace for a REST call
or a Git push is requested.

Force logging means that all log statements will be written
to the error log regardless of the severity of the log statement and the
configured log levels.

This allows to get more information about single requests and makes
debugging them easier.
