Make JetLightClass analyze the whole project (with no caching, for now). This change is related to the following issues:

KT-1474 Execption when running kotlin project
KT-1501 Run script doesn't work in IDEA
In seems that to fix the problem completely, we need to avoid importing Java's default package into every file, but the problems reported in these requests are gone now.

#KT-1501 Fixed
#KT-1474 Fixed
