BAEL-2804 JPA Query Parameters Usage - formatting issues fixed

I fixed some formatting issues as requested since the eclipse formatter
does not support 4 spaces for blocks a 2 for continuations hence it has
to be resolved manually.

Additionally I've applied formatting to the logback.xml file.

persistence-modules/java-jpa-2/src/main/resources/logback.xml
