In raw mode the number of configurations is actively limited to 1. It is
therefore safe to move isRaw up one level to simplify the code and
prepare for later use.
During that rework it was noticed that the old code actually has a bug
in that it reduces the number of configurations to 1 in case a raw
config is found, but it doesn't reduce the config vector to that raw
config, but the first config.
Change that behavior to check the first config and either remove all
remaining configs if the first is raw or drop all raw configs if the
first is non-raw.
