Title: Remove simple redundant return statements for Scala methods/functions

Remove simple redundant return statements for Scala methods/functions:

-) Only change simple return statements at the end of method
-) Ignore the complex if-else check
-) Ignore the ones inside synchronized
-) Add small changes to making var to val if possible and remove () for simple get

This hopefully makes the review simpler =)

Pass compile and tests.
