Fixes start logging if incorrect config

[asm0dey]

If the application can not find the path.properties file for whatever
reason, it won't even log the error because the logger fiesd is not
initialized yet to th moment when the loadAppProperties function
called.

Also, the log line is incorrect, it should contain {} to actually
allow logging of the missing path.

Also, it makes sense to log the absolute path instead of relative for
user to know where to look for it.
