Fix/changing options from sources should not require reload (#3112)

* Test dependencies being removed from classpath after changing the directives in sources and compiling

* Pass only options from cli as initial reloadable bsp options. Those are later embedded in every call to compile or build in BspImpl.run() -> newBloopSession().

* Fix test conditions

* Reloadable options reference should only contain options from CLI in all its fields.

* Apply scalafix

* Review fix
